Q49 / 180 · COMEDK 2014 · Chemistry
The major product obtained when chlorobenzene is nitrated with $\mathrm{HNO}_{3}+$ conc. $\mathrm{H}_{2} \mathrm{SO}_{4}$ is
- Correct answerA1-chloro-4-nitrobenzene
- B1 -chloro-2-nitrobenzene
- C1-chloro-3-nitrobenzene
- D1-chloro-1-nitrobenzene
Solution
The given reaction takes place as follows :
Chlorine is a $o, p$-directing and deactivating group. Chlorine is deactivating because of its $-I$-effect. As inductive effect is distance dependent so, electron density is lower at ortho position than para position. Thus, the nitration occurs at para position.
