Question

chlorination of nitrobenzene under conditions of electrophilic aromatic substitution occurs?

a. Faster than chlorination of benzene and gives a mixture containing mostly o- and p-chloronitrobenzene.
b. faster than chlorination benzene and gives mostly m-chloronitrobenzene.
c. slower than chlorination of benzene and gives a mixture containing mostly o- and p-chloronitrobenzene.
d. slower than chlorination of benzene and gives mostly m-chloronitrobenzene

Answer 1

I believe the nitro group is a deactivating group; thus, the reaction is metal-directing plus the reaction is slower. You may want a second opinion since I'm not an o chemist. Look in your organic text under nitrobenzene and see if you can confirm that.
