Question

Assertion : The presence of nitro group facilitates nucleophilic substitution reactions in aryl halides.
Reason : The intermediate carbanion is stabilised due to the presence of nitro group.

• A. If both assertion and reason are true and reason is the correct explanation of the assertion
• B. If both assertion and reason are true but reason is not the correct explanation of the assertion
• C. If assertion is true, but reason is false
• D. Both assertion and reason are false statements

Answer 1

Answer: (A)

Nitro group is a electron-withdrawing group ( $-I$ groups) It stabilise the carbanion because it disperse the negative charge on the carbon by attracting electrons or negative charge. So both the statements are true and correct explanation.
