Question

016 Friedel-Craft's reaction does not occur in case
of -
(1) Toluene
(3) Naphthalene
(2) Benzene
(4) Pyridine​

Answer 1

Answer:

4

Because Pyridine is a base

as you know we use anhydrous AlCl3 in Reaction

that is Lewis Acid

Pyridine reacts with it and form salt

so frieldal craft Reaction not occurs

Answer 2

Friedel-Craft's reaction does not occur in case of Pyridine.

FRIEDEL-CRAFT'S REACTION:

• Friedel craft's reaction is an example for substitution reaction in which alkylation is done.
• This reaction takes place in the presence of aluminium chloride which is a lewis acid.
• Pyridine will not show this reaction.
• This is because the ring contains nitrogen which in turn has lone pair in it.
• The lewis acid will react with the lone pairs.
• Hence friedel craft's reaction will not be shown by pyridine.
