In this video I will explain why water is more acidic than methane. It is critical that an organic chemistry student is able to not only predict what protons on a molecule are acidic but why they are the most acidic. In this video I will demonstrate the steps that a student should use to explain the differences in pka (ka). pka = -log ka. The large the ka the more acidic a molecule is. The lower the pka the more acidic a molecule is. Consider the following reaction: HA + H2O - H3O+ + A- The ka expression for the above reaction would be: ka = [H3O+][A-]/[HA]. To achieved a large ka using the above expression the concentration of H3O+ and the conjugate base(A-) must be large and the concentration of the parent acid must be low. In other words the more the reaction favors the right side of the reaction the more acidic it is. When comparing two different molecules it is important to understand that acidity is referring to the ka and ka is referring to the concentration of H3O+ and the conjugate base (A-). The higher the concentration of conjugate base at equilibrium the more to the right the reaction is. It stands to reason that if we can predict the relative basicity of two conjugate bases we can predict how far to the right a reaction goes and therefore predict which parent acid is more acidic. In organic chemistry I (Intro to organic chemistry) it is important to be able to identify the acidic protons (hydrogens) and be able to predict how strong or weak the conjugate base will be. An important factor that effects the conjugate base is resonance. If a conjugate base resonances it is likely to be less basic and therefore more stable in water. Remember the stronger the acid the weaker the conjugate base. Strong acids have weak conjugate bases. Strong bases have weak conjugate acids. Acids and bases are important. I wish you all success in organic chemistry. Being able to push arrows and draw resonance forms is a critical skill that you must learn to be successful in organic chemistry. Performing acidity practice problems will help you be successful in organic chemistry. This video is part of a series called How to be Successful in Organic Chemistry. It this series I go over numerous problems that a student could expect to see in there organic chemistry 1 course.

In this video I will explain the difference in pka between acetic acid (carboxylic acid) and chloroacetic acid (carboxylic acid). It is critical that an organic chemistry student is able to not only predict what protons on a molecule are acidic but why they are the most acidic. In this video I will demonstrate the steps that a student should use to explain the differences in pka (ka). pka = -log ka. In general when examining conjugate bases and attempting to determine which one is more basic it is resonance we turn to for the answer. However, if both conjugate bases have equal resonance forms then we must turn to induction for the answer. Induction or the inductive effect is the pulling of electron density through the sigma bonds. Induction is the result of an electronegative atom being bonded to carbon thus making the carbon more positive (delta positive, partial positive). Consider that if a negatively charged atom is attached to a carbon with a greater delta positive charge than typical the more attracted the anion will be to that carbon and the less attractive other cations (protons) will be to the anion. The large the ka the more acidic a molecule is. The lower the pka the more acidic a molecule is. Consider the following reaction: HA + H2O - H3O+ + A- The ka expression for the above reaction would be: ka = [H3O+][A-]/[HA]. To achieved a large ka using the above expression the concentration of H3O+ and the conjugate base(A-) must be large and the concentration of the parent acid must be low.

Resonance forms of carbonyl containing molecules are extremely important concepts in organic chemistry. This video will go over the resonance of a ketone and an ester. If you are able to draw the correct resonance forms of an carbonly containing compounds you can predict the reactivity of a molecule by knowing where an partial negative (delta negative) and partial positive (delta positive) are located on a molecule. Resonance involves arrow pushing. Arrow pushing involves the movement of electrons. For resonance arrow pushing involves the pi electrons only. It is very important that you become skilled at pushing arrows for resonance as it will be a valuable skill when you move into mechanisms.

Resonance forms of anions is an extremely important concept in organic chemistry. In organic chemistry a common anion is the enolate (carbanion beside a carbonyl). In this video I will discuss how to do resonance of an enolate that has two carbonyls that it can resonate with. I will show you how to handle this and how to draw it clearly. Being able to do resonance forms of anions will enable you to understand acidity of organic acids at a very high level! Anions that have the ability to resonance are more stable than anions that cannot resonate. Resonance allows an anion to move the negative charge to more than one atoms thus making each atoms somewhat negative but not a full negative. Resonance involves arrow pushing. Arrow pushing involves the movement of electrons. For resonance arrow pushing involves the pi electrons only.

Banana Boat Sunscreen Recalled due to Cancer Risk Benzene, Cancer Sunscreen #shorts A product intended to prevent skin cancer has been discovered to contain a known cancer causing chemical called benzene. A popular sunscreen, Banana Boat, has issued a voluntary recall for the product Banana Boat Hair and Scalp Spray SPF 30 due to the presence of a known carcinogen called benzene. The manufacturer, Edgewater Personal Care, detected the presence of this chemical during its own internal audits. Benzene is a dangerous, volatile and toxic liquid hydrocarbon that is not intended for human use. Long term exposure to benzene is potentially life threatening and could result in cancers including leukemia, bone marrow cancer and other blood disorders. Although Benzene is not an ingredient in any product manufactured by Banana Boat it is part of the propellant that sprays the sunscreen out of the can. Small amounts of benzene can be found in plastics, detergents, tobacco smoke, motor vehicle exhaust and industrial emissions. If you use Banana Boat Products look for the following batch numbers 20016AF, 20084BF and 21139AF and stop using it if you have any concerns. Good Luck and Good Chemistry!

Skittles Titanium dioxide Lawsuit! Is it safe to eat? #shorts Is candy safe to eat? You may have heard of the skittles lawsuit involving the food additive titanium dioxide. The lawsuit accuses Mars Inc. the maker of skittles of knowingly using an unsafe ingredient in its product. Is titanium dioxide dangerous? What is titanium dioxide? Does skittles contain a dangerous chemical? The food additive titanium dioxide is under a lot of scrutiny for its links to cancer in animal studies. It has been banned as a food additive in the European Union, but is still allowed in Canada, Great Britain and the United States. Titanium dioxide (TiO2) is an inorganic chemical commonly used as a whitener in products like candy, toothpaste, sunscreen and household paint. TiO2 pigments are valued at over $13 billion. TiO2 has been linked to serious health problems including intestinal inflammation, damage to the immune system and cancer in animal studies. This data empowered France to implement a total ban on TiO2 in 2020 and the entire European Union followed in February of 2022. Even the defendant of this lawsuit, Mars Inc. committed in 2016 to phasing out the use of TiO2. However, according to the lawsuit, they have failed to do so. Is TiO2 dangerous? One one hand the European Union considers it a health risk and has banned its use. On the other hand the American, Canadian and British governments says its safe. Good Luck and Good Chemistry!

Shellac makes candy shiny and comes from bugs. Confectioners glaze is used in the production of candy and chocolate to give candy and chocolate that amazing shiny finish. Shellac is also historically used on finished wood products to make them shiny. Did you know that the material that makes wood furniture shine is also used to make candy shine? And that this all revolves around an Asian insect? Lets find out… Candy manufacturers use a material called Confectioner's Glaze to give candy and chocolate the amazing shiny appearance. Confectioner’s Glaze is a solution of shellac and ethanol. Shellac has been used historically to put a shine on wood furniture Shellac is produced from the secretions of the female lac bug. The lac bug infests a tree and over time the female lac bug will cover the branches with a resin called lac. For the lac bug this resin offers protection for her and her offspring. For humans the lac is harvested, placed into a burlap bag and heated. The lac melts and seeps out of the burlap leaving the branches, insect parts and other impurities behind. Lac is further purified and sold as flakes. When dissolved ethanol creates liquid shellac also called Confectioner’ Glaze. So tonight when you are chowing down on your jelly beans consider thanking a Lac bug. She was using her secretions to shelter her offspring while we use it to make stuff shiny! Enjoy!

This video discusses how to convert a number in standard notation into a number in scientific notation. Scientific notation is a convenient way write very large and very small numbers. All numbers written in scientific notation contain a coefficient followed by “x 10” followed by an exponent superscripted to the right of the 10. The exponent tells the reader how many tens (10’s) to multiply or divide the coefficient by. Converting into or out of scientific notation is made very easy using what I call the Bunny Trick!

This video discusses how round numbers properly. Rounding a number is an easy yet very important skill. Indeed, after performing any data manipulation in science you are likely going to have to round the answer your calculator gives you. Here are the rules: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. For example, 129 would could round to 130 if you wanted two (2) significant figures. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. For example, 234 would round to 230 if you wanted two (2) significant figures. Good Luck and Good Chemistry!
