Vedclass · Answer

(B) molecule is chiral if it lacks a plane of symmetry $(P.O.S.)$ or any other improper axis of rotation.Structure $(I)$: This molecule has a plane of symmetry passing through the oxygen atom and the center of the anhydride ring. Thus,it is achiral.Structure $(II)$: This molecule lacks a plane of symmetry. Thus,it is chiral.Structure $(III)$: This is a Fischer projection of a sugar derivative which lacks a plane of symmetry. Thus,it is chiral.Structure $(IV)$: This molecule has a plane of symmetry passing through the central carbon atom. Thus,it is achiral.Structure $(V)$: This is a substituted cycloheptanone which lacks a plane of symmetry. Thus,it is chiral.Therefore,the chiral structures are $(II, III, V)$.The correct option is $(B)$.

List-$I$ (Pair of Compounds)	List-$II$ (Isomerism)
$A$. $n$-propanol and Isopropanol	$(I)$ Metamerism
$B$. Methoxypropane and ethoxyethane	$(II)$ Chain Isomerism
$C$. Propanone and propanal	$(III)$ Position Isomerism
$D$. Neopentane and Isopentane	$(IV)$ Functional Isomerism
