What will be the major product in the following mononitration reaction?
- a
- b
- c
- d✓
Nitration occurs preferentially on the more electron-rich ring:
- Ring A (activated by ): more reactive
- Ring A is ortho/para directed by
- Para position of Ring A (para to N) = major product
Product = (4-nitrobenzanilide)
Key Points:
- Benzanilide: ring with group is activated; ring with is deactivated
- Nitration occurs on the more reactive (amino) ring
- directs ortho/para; para preferred (less steric)
- Product: para-nitro on the N-phenyl (aniline) ring
