The increasing order of nitration in the acidic medium of the following compounds is:
Options
- Aa < b < d < c
- Ba < b < c < d
- Cb < a < c < d
- Db < a < d < c
Correct answer
A. a < b < d < c
Step-by-step solution
– OCH 3 = + M effect so, ring activating group and ortho para directing. – CH 3 = + hyperconjugation & + I so, ring activating group (ortho para directing). – NH 2 = Here the aniline is the least reactive due to formation of anilinium ion in acidic medium. It will now act as strong - I group. – Cl = – I > + M so, ring deactivating & meta directing.
