Consider the above reaction. The number of

π

electrons present in the product 'P' is ____.

Answer: 2

Solution

The reaction shows an elimination reaction where the chloroalkene undergoes dehydrohalogenation with alcoholic KOH to form an alkene product P.

The product P contains one carbon-carbon double bond (

C = C

). Each

π

bond contributes 2

π

electrons.

Therefore, the number of

π

electrons in product P = 2
