Question

The alkene formed as a major product in the above elimination reaction is

Answer 1

Correct Option (b) CH₂ = CH₂

Explanation:

Compounds bearing a quaternary nitrogen atom bonded to four alkyl groups when heated in the presence of base like OH^- undergo E₂ elimination with the formation of less substituted alkene as a major product with the loss of β - H atom.

This type of elimination is called Hofmann elimination.
