Which of the following reaction will give the major and minor products.

CH3−CH2−C∣BrH−CH3→alc.KOHheatCH_{3} - CH_{2} - \underset{\underset{Br}{|}}{C}H - CH_{3}\underset{heat}{\overset{\quad alc.KOH\quad}{\rightarrow}}

A

(1) is major product and (2) is minor product.

B

(1) is minor product and (2) is major product

C

Both (1) and (2) are major products.

D

Only (2) is formed and (1) is not formed.

Answer

(1) is major product and (2) is minor product.
