Multiple Choice Options
- A A < B < C < D
- B D < A < C < B
- C D < B < A < C
- D B < C < A < D
Step-by-Step Verified Solution
In aromatic electrophilic substitution reaction, electrofile attacks to the ring whose electron density is more. 
Note : -M effect is more powerful than -I effect, that is why electron density will be less in the ring for -M effect.
