Why is an amide less reactive to nucleophilic acyl substitution than an acid chloride?
Nitrogen donates more electron density into the carbonyl.
in the presence of strong acids, which of the oxygen atoms on the carboxyl group is preferentially protonated and why?
Protonation occurs at the carbonyl oxygen because the resulting conjugate acid is stabilized by resonance
What is the first step in nucleophilic addition conditions?
Protonation of the carbonyl
