Q12 / 120 · JEE Main 2007 · Chemistry

Presence of a nitro group in a benzene ring

A
activates the ring towards electrophilic substitution
B
renders the ring basic
C
deactivates the ring towards nucleophilic substitution
Correct answer
D
deactivates the ring towards electrophilic substitution

Solution

$-\mathrm{NO}_2$ group shows $-\mathrm{M}$ effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution. Hence, (D) is correct.

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