Question

$C_{6} H_{6} C l_{6}$ on treatment with $KOH$ produce :

• A. $C_{6} H_{6}$
• B. $C _{6} H _{6} Cl _{4}$
• C. $C _{6} H _{3} Cl _{3}$
• D. $C _{6} H _{6} OH$

Answer 1

Answer: (C)

Gammexane $C _{6} H _{6} Cl _{6}$ on reaction with $KOH$ undergo dehydrohalogenation to give $C _{6} H _{3} Cl _{3}$
$C _{6} H _{6} Cl _{6}+\underset{(\text { alc. })}{3 KOH } \rightarrow 3 KCl +3 H _{2} O + C _{6} H _{3} Cl _{3}$
