Which of the following statements is/are correct ?

Options

A. The nitration of phenol is faster than phenyl accetate.
B. The reaction of `PhO^(-)` is faster than
C. Base-cataysed hydrolysis of p-nitrophetyl accetate is fasrter than phenyl acetate.
D. Acid-cataylsed esterification of PhOH is faster than p-nitrophenol with MeCOOH.

Answer

A, B, C, D

Explanation

a. Correct. SE reaction is favoured by EDG, less favoured by EWG.
(I) (II)
Due to cross-conjugation in (II), `bar e`-donating power of oxygen to the ring decreases and hence it is less reactive than (I).
b.
Simce, `PhO^(-)` is a stronger nucleophile than `p-NC--C_(6)H_(4)O^(-)`. Hence, it reacts faster with `PhCH_(2)CI`.
c.
As we know, (I) is faster than (II). The `bar e` withdrawing effect of `(p-NO_(2))` group `(--R` and `--I)`, form O makes `p-NO_(2)---C_(6)H_(4)---O^(-)` a weaker base and better leaving group.
d. Esterification of PhOH is faster than p-nitrophenol. Phenol, a less acidic compound (or more basic) is more reactive in acidic condition. With its `bar e`-withdrawing `(p-NO_(2))` group, p-nitrophenol is less basic and less reactive.
