| \[C{{H}_{3}}-CH\underset{(A)}{\mathop{=}}\,CH-C{{H}_{3}}+C{{H}_{3}}-C{{H}_{2}}\underset{(B)}{\mathop{-}}\,CH=C{{H}_{2}}\] |
A) [A] is major product and [B] is minor product.
B) [A] is minor product and [B] is major product.
C) Both [A] and [B] are major products.
D) Only [B] is formed and [A] is not formed.
Correct Answer: A
