Question

Compound $X$ can exist in how many orientations?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

There is one chiral center that gives two optical isomers which are enantiomers and the presence of different groups at carbon double bond gives geometrical isomers (E and Z) as shown.

Therefore there are total of 4 orientations/isomers possible for X. Option D is correct.
