Esters and amides are most easily made by nucleophilic acyl substitution reactions on ________.

A) alcohols.
B) acid anhydrides.
C) carboxylates.
D) carboxylic acids.
E) acid chlorides.

Nucleophilic Acyl Substitution

A type of organic reaction where a nucleophile replaces a leaving group in an acyl compound, forming a new covalent bond.

Esters

Organic compounds derived from an acid where at least one -OH (hydroxyl) group is replaced by an -O- (alkoxy) group, known for their fruity smells.

Amides

Organic compounds containing a carbonyl group linked to a nitrogen atom from an amine, fundamental in the structure of proteins.
