Question

Nitration of nitrobenzene mechanism gives m-dinitrobenzene in high temoerature or room temperature ?

Answer 1

Explanation:

It's because the NO₂ group is electron-withdrawing. As it has no lone pairs to donate and has electronegative atoms it tends to remove some of the delocalised electrons from the benzene ring, making it less vulnerable to electrophilic attack. Why is the nitration of nitrobenzene slower than the nitration of benzene
