How many different stereoisomers are possible for the given molecule ? CH3 – CH – CH = CH – CH3 OH

1. 3
2. 1
3. 2
4. 4

Correct answer: 4

Solution

The molecule has two double bonds, which can each exhibit cis-trans isomerism, leading to multiple stereoisomers. Specifically, the presence of two double bonds allows for a combination of configurations, resulting in a total of four distinct stereoisomers.
