The hydrolysis of an amide often requires harsh conditions, high temperatures, or a special enzyme. Identify which of the following statements does NOT provide a reason for this lack of reactivity. A) The pka of NH* is ~10 and the pka of H₂O is -16. B) The nitrogen of the amide can donate electrons to make a resonance structure that stabilizes the partial positive charge on the carbon. C) -NH, is not as stable of a leaving group as - OH, since it is less electronegative. D) There is significant 'double-bond' character between the carbon and nitrogen in an amide.

B) The nitrogen of the amide can donate
electrons to make a resonance structure that
stabilizes the partial positive charge on the
carbon.
C) -NH, is not as stable of a leaving group as -
OH, since it is less electronegative.
D) There is significant 'double-bond' character
between the carbon and nitrogen in an amide.

Proteins are long chains of repeating amino acids connected by peptide bonds.
The reverse reaction of peptide bond formation is the hydrolysis of an amide.
Peptide bonds are
A) very reactive with water
B) unreactive with water but easily hydrolyzed
under acidic conditions
C) unreactive with water but easily hydrolyzed
under basic conditions
D) unreactive with water and only slightly
reactive to hydrolysis under acidic conditions
