प्रश्न
Explain optical isomerism in 2-chlorobutane.
Advertisements
उत्तर
- The stereoisomerism in which the isomers have different spatial arrangements of groups/atoms around a chiral atom is called optical isomerism.
- 2-chlorobutane has one chiral carbon atom. The spatial arrangement of the four different groups around the chiral atom is different.
- Structure of 2-chlorobutane and its mirror image can be represented as:
- 2-Chlorobutane cannot superimpose perfectly on its mirror image as shown in the figure. Hence, 2-chlorobutane exhibits optical isomerism.
