Q. Give reasons for the following:
(a) Acetylation of aniline reduces its activation effect.
(b)

C H_{3} N H_{2}

is more basic than

C_{6} H_{5} N H_{2}

N H_{2}

is O/P directing group,
yet aniline on nitration gives a significant amount of m - nitroaniline.

Give reasons of the following:

- N H_{2}

is o/p directing group, yet aniline on nitration gives a significant amount of m-nitroaniline

- {N H}_{2}

group of aniline is ortho, para directing in electrophilic substitutions. Reason:

- {N H}_{2}

group stabilises the arenium ion formed by the ortho, para attach of the electrophile

Statement: In case of meta-attack on aniline (where

{N H}_{2}

group is o-, p-directing) and in case of ortho-attack on nitrobenzene, resonating structures are possible. Meta-attack is more stable.

State whether the given statement is true or false.

Q. Which of these is o, p-directing and deactivating group?
