Question

When chlorine is passed through propene at $${400^ \circ }C,$$  which of the following is formed?

A. $$PVC$$
B. Allyl chloride  
C. Nickel chloride
D. 1, 2 - dichloro ethane
Answer :   Allyl chloride
Solution :
When chlorine gas is reacted with propene at high temperature $$\left( {{{400}^ \circ }C} \right),$$   then substitution occurs in place of addition reaction. Hence, allyl chloride is formed
