Open in App
Solution
The correct option is D Nitrobenzene
Diazonium cation is a weak electrophile and hence it reacts with electron-rich compounds containing electron-donating groups such as −OH, −NH2 and OCH3 groups and not with compounds containing electron-withdrawing groups such as −NO2, etc.
Hence, option D is correct.
