Why are aldehydes more reactive than ketones toward nucleophilic attack Aldehydes have a larger dipole moment Ketones have a higher molecular weight Aldehydes have an acidic proton attached to the carbonyl group Ketone are stabilized by electron donating alkyl groups Which of the following are NOT true of nucleophilic attacks on aldehydes and ketones ? Each step of acetal formation is reversible and the acetal and carbonyl exist in an equilibrium Attach of Grignard reagents or hydride reagents are effectively irreversible Primary, secondary, and tertiary amines will add to form imines Addition to the carbonyl can either be acid or base catalyzed Why are carboxylic acids so much more acidic than the corresponding alcohols Carboxylates can delocalize the negative charge over 2 resonance forms while alkoxides can't Carboxylic acid have 2 OH sites that can be deprotonated Carboxylic acids have a neutral and charged resonance form while alcohols don't Carboxylic acids are more polar than alcohols
