Question

which of the following will have a meso isomer also

(a) 2,3-dichlorobutane

(b) 2-chlorobutane

(c) 2,3-dichloropentane

(d)2-Hydroxy propanoic acid

Answer 1

The isomer which has more than one chiral carbon and it is also an optically inactive isomer then it is called meso isomer.

so here 2,3 dichlorobutane has more than one chiral carbon and it is also not equally inactive isomer due to presence of pos.

So option a is the correct answer.



PLEASE MARK BRAINLIST.
