Which of the following undergo nitration more slowly than benzene?

Question

Quizplus · Accepted Answer

Compounds 2 and 3 contain electron-withdrawing groups (carbonyl and nitro groups), which decrease the electron density on the ring and make it less reactive towards electrophilic substitution reactions like nitration. Therefore, they undergo nitration more slowly than benzene. Compounds 1, 4, and 5 either do not have any substituents or have electron-donating substituents, which increase the electron density and make them more reactive towards nitration than benzene.
