Which of the following compounds can exist both as a cis pair of enantiomers and a trans pair of enantiomers?

Options

A. `CH_(2) =CHCHCICH =C(CH_(3))_(2)`
B. `CH_(3)CHCICH = CH_(2)`
C. `CH_(3)CHCICH =CHCH_(3)`
D. `CH_(2)=CHCH(OH)CH=CH_(2)`

Answer

C

Explanation

This is possible provided the molecule of compound has a chiral carbon atom and is capable of exhibiting geometrical isomerism.
`underset(5)CH_(3)overset(**)underset(4)(CH)CIunderset(3)CH=underset(2)CHunderset(1)CH_(3)`
Each of the doubly bonded carbon atom carries different ligands (This leads to geometrical isomerism). There is just one chiral carbon `(C-4)`which leads to enantiomerism
