Chapter 21, Problem 21.4P

Interpretation Introduction

Interpretation:

Whether the hydrolysis of phenyl acetate is faster or slower than the hydrolysis of ethyl acetate is to be determined.

Concept introduction:

If the carbonyl group is stabilized by resonance, it is less reactive. So in this case, the rate of hydrolysis of ester is slower.

If the carbonyl group is less stabilized by resonance, it is more reactive. So in this case, the rate of hydrolysis of ester is faster.
