Assertion (A) \(-\mathrm{NH}_2\) group of aniline is ortho, para directing in electrophilic substitutions. Reason (R) \(-\mathrm{NH}_2\) group stabilises the arenium ion formed by the ortho, para attack of the electrophile. The correct answer is
- A Both \((A)\) and \((R)\) are correct, \((R)\) is the correct explanation of \((A)\)
- B Both \((\mathrm{A})\) and \((\mathrm{R})\) are correct, \((\mathrm{R})\) is not the correct explanation of \((\mathrm{A})\)
- C (A) is correct, but (R) is not correct
- D (A) is not correct, but (R) is correct
Answer & Solution
Correct Answer
(A) Both \((A)\) and \((R)\) are correct, \((R)\) is the correct explanation of \((A)\)
Step-by-step Solution
Detailed explanation
The \(-\mathrm{NH}_2\) group of aniline is a very strong electron donor (+ \(M\) effect), hence it activates the benzene ring thoroughly and the electrophilic aromatic substitutions on the benzene ring are very easy to take place at ortho and para-positions.
