Question

What would be the major monochloro product formed when trifluoromethyl benzene react with chlorine in the presence of ferric chloride?​

Answer 1

Explanation:

In presence of FeCl3 and in dark, electrophilic substitution on benzene ring by Cl

In presence of FeCl3 and in dark, electrophilic substitution on benzene ring by Cl +

In presence of FeCl3 and in dark, electrophilic substitution on benzene ring by Cl + ion at ortho and para positions occurs to give o- and p-chlorotoluene.

In presence of FeCl3 and in dark, electrophilic substitution on benzene ring by Cl + ion at ortho and para positions occurs to give o- and p-chlorotoluene.Since the methyl group activates the ring at ortho and para position more than meta position, the electrophilic substitution occurs mostly at these positions.

In presence of FeCl3 and in dark, electrophilic substitution on benzene ring by Cl + ion at ortho and para positions occurs to give o- and p-chlorotoluene.Since the methyl group activates the ring at ortho and para position more than meta position, the electrophilic substitution occurs mostly at these positions. Again, amongst these, the para isomer is the major product due to steric reasons.

Again, amongst these, the para isomer is the major product due to steric reasons. Hence the correct option is D.

Answer 2

Answer:

As CF3 is a meta director so Cl will be placed at meta position as a result of electrophilic substition reaction in presence of chlorine.
