Consider the following reaction:        Which of the following options is CORRECT about  and ?

A)

(A)	(B)

B)

(A)	(B)

C)

(A)	(B)
	\[MeHC=C=CHMe\]

D)

(A)	(B)
\[MeHC=C=CHMe\]

Correct Answer: C

Solution :

[c] D.U. of [a] and [b] is \[2{}^\circ \] and \[1{}^\circ ,\] respectively. [a] and [b] must have 4C or 5C-ring, but 5C-ring alkene will not show optical isomerism. So structure of Similarly, D.U. of[c] and [d] = 2 and 0, respectively. [c] and [d] cannot have ring; therefore, only alkenes with two different groups are resolvable. So the structure of [c] is:
