Q21 / 160 · AP EAMCET 2010 · Chemistry

In which of the following, ortho/para substitution by an electrophile is very facile?

A
Nitrobenzene
Correct answer
B
Phenol
C
Benzoic acid
D
Acetophenone

Solution

- OH group is ortho/para directing and makes the benzene ring more active towards electrophilic substitution. Thus, ortho/para substitution in phenol by an electrophile is very facile.

Hence, the correct answer is option: 'B'.
