Question
Assertion :Nitrobenzene undergoes electophilic substitution at m−position, while nucleophilic substitution occurs ar o− and p− position. Because Reason: Nitro group in benzene ring significantly lowers the electron density at o− and p− positions, while at m− position, the electron density is only slightly lowered

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.Nitrobenzene undergoes electophilic substitution at m−position, while nucleophilic substitution occurs at o− and p− position. The nitro group exhibits −M effect which withdraws the electrons and in benzene ring significantly lowers the electron density at o− and p− positions, while at m− position, the electron density is only slightly lowered only where an electrophile can attack.
