Question

How propene is prepared from 1,2 dichloropropane??​

Answer 1

Alkali wash of 1,2 dichloropropane followed by treating with concentrated H2SO4 leads to propene.

Explanation:

• Propene is the alkyne having 3 carbons.

• The 1,2 dichloropropane is the chloro carbon with chlorine on 2 consecutive carbon atoms.

• With dilute KOH wash, the chlorine groups of the 1,2 dichloropropane is converted to hydroxyl groups.

• So the product is 1,2 propan diol.

• This when treated with concentrated Sulphuric acid undergoes dehydration to produce propene.
