ANSWER

In the presence of alc. KOH

Reaction of the process:

CH

3

−CH

2

Cl+KOH→CH

2

=CH

2

+KCl

In this process Alc. KOH is used for dehydrohalogenation.

Then in presence of HBr

CH

2

=CH

2

+HBr→CH

2

Br−CH

3

So CH

2

=CH

2

(X) obtained from CH

3

CH

2

Br(Y) by dehydrohalogenation means by elimination of HBr.

Is this the answer you want? If yes pl thank me

Answer 2

CH3X>CH3CH2X>CH3CH2CH2X Alkyl group increases order of reactivity decreases due to bulky group.
