MCQ
Chloroethane is reacted with alcoholic potassium hydroxide. The product formed is:
- AC2H6O
- BC2H6
- CC2H4
- DC2H4O
✓
Answer
- C2H4
Explanation:
Chloroethane reacts with alc.KOH and ethene forms.
It is a basic method for preparation of alkene.
Alcoholic KOH when used the elimination reaction takes place.
$\text{C}_2\text{H}_5\text{Cl}\xrightarrow{\text{alc.KOH}}\text{C}_2\text{H}_4+\text{HCl}$
