Vedclass · Answer

(B) molecule is optically inactive if it does not rotate the plane of polarized light. This occurs if the molecule is achiral,which can happen due to the presence of a plane of symmetry (internal compensation) or if it is a racemic mixture (external compensation). In the given options,$cis$-$1,2$-dimethylcyclopentane has a plane of symmetry passing through the carbon atoms $C_1$ and $C_2$ (bisecting the bond between them),making it a meso compound. Meso compounds are achiral and therefore optically inactive. Thus,the correct option is $B$.

Column-$(I)$	Column-$(II)$
$(A)$ $C_2H_5-C(CH_3)(OH)-H$	$(p)$ $Cl-C(Br)(I)-H$
$(B)$ $Br-C(Cl)(I)-H$	$(q)$ $OH-C(CH_3)(C_2H_5)-H$
	$(r)$ $H_5C_2-C(OH)(CH_3)-H$
	$(s)$ $Cl-C(I)(Br)-H$
