Question

Convert chloroethan to benzene

Answer 1

Answer:

Explanation:

First convert Ethane to Ethylene by pyrolysis (heating at high temperature)

C3H6−→ΔC2H4+H2↑

Do chlorination of the Ethylene to get Ethylene dichloride

C2H4+Cl2→ClH2C−CH2Cl

Treat this Ethylene dichloride with alcoholic potassium hydroxide to get acetylene & Potassium chloride

CH2Cl−CH2Cl+2KOH(alc)−→−−−alcoholC2H2+2KCl+2H2O

Pass this acetylene through red hot iron tube at 873K to get required Benzene
