Aniline dose not undergo

Options

A. Friedel Carafts alkylation Friedel Crafts alkylation
B. Friedel Carafts acylation
C. Both of these
D. None of these

Answer

A

Explanation

Aniline does not undergo Friedel-Crafts reaction (alkylation as well as acylation) due to salt formation with aluminium chloride the Lewis acid which is used as a catalyst to generate electrophile
`underset("Lewis base")(C_(6)H_(5)NH_(2))+ underset("Lewis acid")(AICI_(3))rarrC_(6)H_(5)underset(Sal t)overset(+)(NH_(2))-barAICI_(3)`
Due to this nitrogen of aniline acquires positive charge and hence acts as a strong deactivator for the electrophilic substitution Moreover `AICI_(3)` is not available to generate electrophile .
