Given below are two statements:
Statement (I) : The $\mathrm{NH}_{2}$ group in Aniline is ortho and para directing and a powerful activating group.
Statement (II) : Aniline does not undergo FriedelCraft’s reaction (alkylation and acylation).
In the light of the above statements, choose the most appropriate answer from the options given below :
(1) Both Statement I and Statement II are correct
(2) Both Statement I and Statement II are incorrect
(3) Statement I is incorrect but Statement II is correct

Show Answer
Answer (1)
Solution
The $\mathrm{NH}{2}$ group in Aniline is ortho and para directing and a powerful activating group as $\mathrm{NH}{2}$ has strong $+\mathrm{M}$ effect.
Aniline does not undergo Friedel-Craft’s reaction (alkylation and acylation) as Aniline will form complex with $\mathrm{AlCl}_{3}$ which will deactivate the benzene ring.
