The following reaction CH(3)-underset(...

The following reaction
`CH_(3)-underset(CH_(3))underset(|)overset(H)overset(|)(C)-underset(X)underset(|)overset(CH_(3))overset(|)(C)-CH_(3)underset(-2O,-KBr)overset(Alc.kOH)(to)`
`CH_(3)-underset(CH_(3))(|)(C)=overset(CH_(3))overset(|)(C)-CH_(3)`
is an example of

A

`alpha`-elimination

B

`beta`-elimination

C

Hofmann elimination

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
`CH_(3)-underset(H)underset(|)overset(CH_(3))overset(|)(C^(b))-underset(X)underset(|)overset(CH_(3))overset(|)(C^(a))-CH_(3) underset(-H_(2)O,-KBr)overset(Alc. KOH)(to)`
`CH_(3)-overset(CH_(3))overset(|)(C)=overset(CH_(3))overset(|)(C)-CH_(3)`
When a haloalkane with `beta` hydrogen atom is heated with alc. `KOH` solution there is elemination of hydrogen atom from `beta`-carbon and a halogen atom from `alpha`- carbon atom `(beta)`-elimination.
