- The following pKa values have been measured. Explain why a hydroxyl group in the para position decreases the acidity while a hydroxyl group in the meta position increases the acidity.arrow_forwardThe following molecule belongs to a class of compounds called enediols. Each carbon of the double bond carries an —OH group: Draw structural formulas for the α-hydroxyketone and the α-hydroxyaldehyde with which this enediol is in equilibrium. α-hydroxyketone α-hydroxyaldehydearrow_forwardion 4 of 15 Urushiol, the component of poison ivy that is responsible for the characteristic itchy rash, is a mixture of catechols substitute with various long-chain alkyl groups. OH (CH,),– CH, pK = 8 Which of these treatments would be most effective at removing catechols from the surface of the skin after exposure to poison ivy? O Wash the area with cold water. O Wash the area with dilute vinegar or lemon juice. Wash the area with soap and water. O Wash the area with soap, water, and baking soda (sodium bicarbonate).

- Phenols are aromatic rings with an alcohol functional group attached directly to the ring. These compounds have unique acidity and solubility for alcohol groups. Predict the solubility of this phenol in water.arrow_forwardThe Brønsted-Lowry definition of acids and bases is: Acids are proton donors, bases are proton acceptors Acids are nucleophiles and bases are electrophiles Acids are proton acceptors, bases are proton donors Carboxy groups are acids and amine groups are bases Carboxy groups are electrophiles and amine groups are nucelophilesarrow_forwardOxidation of aldehyde results in carboxylic aciid in a reaction similar to this: Draw the chemicals that form when the following chemicals are oxidized: a) 3-Chloropropanal b) methanalarrow_forward
- The following molecule belongs to a class of compounds called enediols; each carbon of the double bond carries an-OH group. Draw structural formulas for the a-hydroxyketone and the a-hydroxyaldehyde with which this enediol is in equilibrium. CH-OH a-Hydroxyaldehyde = C-OH= a -Hydroxyketone ČH3 An enediolarrow_forwardExplain why phenol (C6H50H) is substantially more acidic than methanol (CH3OH), but benzoic acid (C6H5CO2H) is not much more acidic than acetic acid (CH3CO2H). Нас — ОН ОН H3C- ОН OH pKa = 15.5 pKa = 10.0 pk = 4.75 pk = 4.2arrow_forwardPart A: Draw the product of the reaction of propylamine with water Part B: Draw the product of the neutralization of propylamine with HBr Part C: Draw the product of the reaction of N-methylaniline with waterarrow_forward
- Acetals are formed from the reaction of two alcohols with a carbonyl under acidic conditions. Acetal formation is faster with 1,2-ethanediol than with two methanol molecules. Choose the factor that explains the difference in reaction rates. A) The reaction with 1,2-ethanediol has a lower AH (enthalpy) of reaction. B) The reaction with 1,2-ethanediol has a higher AH (enthalpy) of reaction. C) The reaction with 1,2-ethanediol has a more favorable entropy of reaction.arrow_forwardName the following organic compound: CH₂ CH₂ H3C CH₂ OH O 2-oxo-5-pentanol O 4-oxo-1-pentanol O 5-hydroxy-2-pentanone O hydroxypentanone O 1-hydroxy-4-pentanonearrow_forward16-13 Classify each amino group as primary, secondary, or tertiary and as aliphatic or aromatic. Serotonin (a neurotransmitter) Diphenhydramine (the hydrochloride salt is the antihistamine Benadryl) Lysine (an amino acid)arrow_forward
