Among the following, the alkene that exhibits optical isomerism is
4-methyl-1-pentene
3-methyl-2-pentene
- 3-methyl-1-pentene
- 2-methyl-2-pentene
- 2,3-dimethyl-2-butene
The Correct Option is B
Solution and Explanation
The alkene that exhibits optical isomerism is 3-methyl-2-pentene.
Explanation:
Optical isomerism occurs when a molecule has a chiral center, i.e., a carbon atom attached to four different substituents. In the case of 3-methyl-2-pentene, the carbon at position 2 is attached to four different groups, making it a chiral center and thus capable of exhibiting optical isomerism. The other alkenes listed do not have a chiral center and, therefore, cannot exhibit optical isomerism.
