Question

Directive influence of a functional group in monosubstituted benzene

Answer 1

$\large{\underline{\rm{\green{Directive\:influence\:of\:a\:functional\:group\: in\:monosubstituted\:benzene:-}}}}$

→ When monosubtituted benzene is subjected to further substitution, three possible disubtituted products are not formed in equal amounts.

→ Two types of behaviour are observed.

→ Basically, as we know the ortho and para products and meta product is formed predominantly.

→ It has also been observed that this behaviour depends on the nature of the substituent already.

present in the benzene ring and not on the nature of the entering group.

→ This is known as directive influence of substituents.
