Vedclass · Answer

(D) chiral object is one that is not superimposable on its mirror image. $A$. $A$ cube is achiral because it has a plane of symmetry and is superimposable on its mirror image. $B$. $A$ human hand is chiral because it is not superimposable on its mirror image (left hand cannot be perfectly superimposed on the right hand). $C$. $A$ human figure (in a standard standing position) is generally considered achiral due to a plane of symmetry. $D$. $3-$methylheptane is a chiral molecule because it contains a chiral center (the carbon atom at position $3$ is bonded to four different groups: $-H$,$-CH_3$,$-CH_2CH_3$,and $-CH_2CH_2CH_2CH_2CH_3$). Since both $B$ and $D$ represent chiral entities,and $3-$methylheptane is the standard chemical example of a chiral molecule,$D$ is the most appropriate answer in a chemical context.
