MCQ
Chloroethane is reacted with alcoholic potassium hydroxide. The product formed is:
  • A
    $\ce{C_2​H_6​O}$
  • B
    $\ce{C_2​H_6}$​
  • ✓
    $\ce{C_2H_4}$​
  • D
    $\ce{C_2H_4O}$
✓

Answer

Correct option: C.
$\ce{C_2H_4}$​
Chloroethane reacts with alc$.\text{KOH}$ and ethene forms.
It is a basic method for preparation of alkene.
Alcoholic $\text{KOH}$ when used the elimination reaction takes place.
$\text{C}_2\text{H}_5\text{Cl}\xrightarrow{\text{alc.KOH}}\text{C}_2\text{H}_4+\text{HCl}$
