The formation of
Concept introduction:
The stability of alkene is depending on the number of alkyl group attached to the carbon atom of the double bond.
The stability of alkene increases as the number of alkyl group attached to the carbon atom of double bond increases.
According to the Zaitsev’s rule, in the presence of small base like hydroxide or ethoxide the more highly substituted alkene will be the major product.
