Question

What happens when ethene gas is treated with HCl?

• A. Ethane is formed
• B. Methane is formed
• C. Chloroethane is formed
• D. Ethylene is formed

Answer 1

The correct option is C

Chloroethane is formed

When ethene gas is treated with HCl,chloroethane or ethyl chloride is formed.

$C{H}_2=C{H}_2+HCl\to$ $C{H}_3-C{H}_2-Cl$

If chloroethane is treated with aqueous potassium hydroxide, ethanol is formed.

$C{H}_3-C{H}_2-Cl+KOH\to$ $C{H}_{3}C{H}_{2}OH+KCl$
