НС — ОН a-hydroxyaldehyde C-OH = a-hydroxyketone CH3 An enediol

Hydration of aldehydes and ketones can be catalyzed by acid or base. Bases catalyze hydration by: protonating the carbonyl oxygen making the carbonyl group more electrophilic employing hydroxide ion, which is a better nucleophile than water making the carbonyl group less electrophilic shifting the equilibrium position of the reaction to favor products

Q: What ester results in the following reflux? pentanoic acid CH₂CH₂OH OH R' R-OH Q: What alcohol and acid must we use to make the following ester? O O H+ OH H+ benzyl isobutanoate H₂O

TRUE OR FALSE; The carbonyl carbon in an amide and the carbon in an aromatic ring have the same hybridization.

Name the following carboxylic acid derivatives, giving both a common name and anIUPAC name where possible.CH3CH(OH)CH2CN

Aldehydes and ketones react with one molecule of an alcohol to form compounds called hemiacetals, in which there is one hydroxyl group and one ether-like group. Reaction of a hemiacetal with a second molecule of alcohol gives an acetal and a molecule of water. ROH, H+ OH OR Aldehyde/ketone Alcohol ROH, H+ Draw the structural formulas for the hemiacetal and the acetal formed between the following compounds: OH OH OR OR • Use the wedge/hash bond tools to indicate stereochemistry where it exists. + H₂O

Why is this compound named 2-Naphthalenecarbaldehyde and not 1-Naphthalenecarbaldehyde?
