Assertion : The reaction of conc. HNO3 a...

Assertion : The reaction of conc. `HNO_3` and conc.`H_2SO_4` on nitrobenzene gives m-dinitrobenzene.
Reason : The nitro group in benzene ring decreases the electron density in the benzene ring.

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.

C

If Assertion is correct , but Reason is incorrect.

D

If both Assertion and Reason are incorrect .

Text Solution

Verified by Experts

The correct Answer is:
B
The nitro group in nitrobenzene mainly decreases the electron density at o- and p- positions and hence is m-directing.
