Answer 2

Answer :

★ Elimination reaction :

Haloalkanes with ß-hydrogen undergo elimination (dehydrohalogenation-elimination of hydrogen from ß-carbon and halogen from α-carbon) when heated with alcoholic solution of KOH$.$

• If there is possibility of formation of more than one alkene due to the availability of more than one ß-hydrogen atoms then the major alkene is one which contains maximum number of alkyl groups. This is know. as Saytzeff's rule.
