MCQ
Which of the following compounds will exhibit cis-trans isomerism
- ✓$2-$butene
- B$2-$butyne
- C$2-$butanol
- DButanone
✓
Answer
Correct option: A.
$2-$butene
a
(a) Cis-trans isomerism shown by compound which have double or triple bond by which they restrict their rotation, since $2-$ butyne have no hydrogen on triple bonded carbon.
