Solution

The correct options are
A Acid-catalysed esterification of PhOH is faster than p-nitrophenol with MeCOOH
B The nitration of phenol is faster than phenyl acetate
C The reaction of $P h O^{⊝}$ is faster than $p - N C - C_{6} H_{4} O^{⊝}$ with $P h C H_{2} C l .$
D Base-catalysed hydrolysis of p-nitrophenyl acetate is faster than phenyl acetate
A. Due to cross-conjugation in phenol, e-donating power of oxygen to the ring decreases and hence, it is less reactive than phenyl acetate.
B. Since, $P h O^{⊝}$ is a stronger nucleophile than $p - N C - C_{6} H_{4} O^{⊝}$ . Hence, it reacts faster with $P h C H_{2} C l .$
C. The e-withdrawing effect of $(p - N O_{2})$ group from O makes $p - N O_{2} - C_{6} H_{4} - O^{⊝}$ a weaker base and better leaving group.
D. Esterfication of PhOH is faster than p-nitrophenol. Phenol, a less acidic compound (or more basic) is more reactive in acidic conditions. With its $¯ e$ -withdrawing $(p - N O_{2})$ group, p-nitrophenol is less basic and less reactive.
