The major product obtained when chlorobenzene is nitrated with HNO ₃+ conc. H ₂ SO ₄ is
Options
- A1-chloro-4-nitrobenzene
- B1 -chloro-2-nitrobenzene
- C1-chloro-3-nitrobenzene
- D1-chloro-1-nitrobenzene
Correct answer
A. 1-chloro-4-nitrobenzene
Step-by-step 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.
