Assertion (A) Nitration of chlorobenzene leads to the formation of m-nitrochlorobenzene.
Reason (R) `-NO_(2)` group is a m-directing group.

Assertion: Nitration of benzene leads to the formation of m-nitro benzene. Reason: -NO_(2) roup is a m-directing group.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I : Nitration of chlorobenzene leads to the formation of ortho and para nitrochlorobenzene. Statement - II : NO_2 group is a o,p-directing group.

The nitro group is a very strong deactivating group Nitro benzene undergoes nitration at a rate only 10-4 times that of benzene. The nitro group is a meta-directing group. When nitrobenzene is nitrated with nitration mixture 93% of meta substituted product is formed. Ortho-para directing groups are

The nitro group is a very strong deactivating group Nitro benzene undergoes nitration at a rate only 10-4 times that of benzene. The nitro group is a meta-directing group. When nitrobenzene is nitrated with nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :

Which of the following groups are m- directing :
