C6H6Cl6C_{6}H_{6}Cl_{6}, on treatment with alcoholic KOHKOH, yields.

A

C6H6C_{6}H_{6}

B

C6H3Cl3C_{6}H_{3}Cl_{3}

C

(C6H6)6muOH(C_{6}H_{6})\mspace{6mu} OH

D

C6H6Cl4C_{6}H_{6}Cl_{4}

Answer

C6H3Cl3C_{6}H_{3}Cl_{3}

Explanation

Solution

C6H6Cl6+3KOHC6H3Cl3+3KCl+3H2OC_{6}H_{6}Cl_{6} + 3KOH \rightarrow C_{6}H_{3}Cl_{3} + 3KCl + 3H_{2}O

Thus Benzene hexahalides decomposes when heated with alc. KOH and yield trichloro benzene.
