`C_(6)H_(6)CI_(6)` on treatment with alcoholic `KOH` yields .

A

`C_6H_6`

B

`C_6H_3Cl_3`

C

`(C_6H_6)OH`

D

`C_6H_6Cl_4`

Text Solution

Verified by Experts

The correct Answer is:
B

`C_6H_6Cl_6+3KOH rarr C_6H_3Cl_3+3KCl+3H_2O`
Thus Benzene hexahalides decomposes when heated with alc. KOH and yield trichloro benzene.
