Question
Which of the following compounds may exist as cis-trans isomers?
Correct Answer
Option B is the correct answer.
Detailed Explanation
2-Butene (CH3CH=CHCH3) can exist as cis and trans isomers because each carbon of the double bond has a methyl group and a hydrogen atom. 1-Butene has CH2 at one end, cyclopropane is a ring, and acetone has no C=C.
Hint
Which compound has a C=C with different groups on each carbon?
