Question

Which of the following is incorrect regarding the use of ethylene?

• A. It is use in the preparation of antifreeze
• B. It is used in the preparation of polymers
• C. It is used in the preparation of lewisite
• D. It is use in the preparation of mustard gas

Answer 1

Answer: (C)

It is used in the preparation of lewisite

Mustard gas:
Sulfur mustard is $(Cl-C{H}_{2}C{H}_2{)}_{2}S$. In the Depretz method, sulfur mustard is synthesized by treating $SC{l}_2$ with ethene.
Antifreeze:
Vicinal diols are a common ingredient of antifreeze and these diols can be made by alkenes.
Alkenes are unsaturated so they can be used for polymerization.
Lewisite can be prepared by
$C_2{H}_2+AsC{l}_3\to ClCHCHAsC{l}_2$
