Vedclass · Answer

(B) When benzene reacts with a nitrating mixture (concentrated $HNO_3$ + concentrated $H_2SO_4$) at $323-333 \, K$,it forms nitrobenzene.However,when nitrobenzene is further treated with the same nitrating mixture at a higher temperature of $353-363 \, K$,the $-NO_2$ group (which is a meta-directing group) directs the incoming second $-NO_2$ group to the meta position.Thus,the final product is $m$-dinitrobenzene.

The product obtained by the reaction of benzene with concentrated $HNO_3$ and concentrated $H_2SO_4$ at $353$ to $363 \, K$ is....
