JEE Advanced levelSingle correct optionDifficulty 3 of 3nc162

Assertion: Direct nitration of aniline with a mixture of conc. and conc. gives a considerable amount of 3-nitroaniline. Reason: The amino group is a meta-directing group.

  1. ABoth Assertion and Reason are true and the Reason is the correct explanation of the Assertion
  2. BBoth Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
  3. CAssertion is true but Reason is false
  4. DAssertion is false but Reason is true

Answer: C

In the strongly acidic nitrating mixture aniline is largely protonated to the anilinium ion, and the group is meta-directing, so appreciable 3-nitroaniline forms. The amino group itself is ortho, para directing, so the Reason is false while the Assertion is true.
