Chlorobenzene is mononitrated with conc. HNOX3 and conc. HX2SOX4. Which statement is correct?
ANitration is slower than for benzene, and the major product is 1-chloro-4-nitrobenzene with 1-chloro-2-nitrobenzene as the minor product
BNitration is slower than for benzene, and the major product is 1-chloro-3-nitrobenzene
CNitration is faster than for benzene, and the major product is 1-chloro-3-nitrobenzene
DNitration is as fast as for benzene, giving equal ortho and para products only
Answer: A
Chlorine deactivates the ring (-I > +R) so the reaction is slower than for benzene, but its +R effect directs to ortho and para. The para product is major because it is less hindered; the ortho isomer is the minor product.
