Question

Which shows the easier electrophilic substitution in ring? (A) N-acetyl aniline (B) C 6 H 5 NH 3 Cl (C) Aniline (D) Nitrobenzene

Tardigrade Admin · Accepted Answer

Ortho and para directing groups facilitate the ring for electrophilic substitution reaction. - NH 2 group increase e-density in ring, hence activate it to electrophilic substitution.

Q. Which shows the easier electrophilic substitution in ring?

N-acetyl aniline

$C_{6} H_{5} N H_{3} Cl$

Aniline

Nitrobenzene

Ortho and para directing groups facilitate the ring for electrophilic substitution reaction. $- N H_{2}$ group increase $e^{-}$ density in ring, hence activate it to electrophilic substitution.
