Vedclass · Answer

(A) compound is optically inactive if it does not contain a chiral center (an asymmetric carbon atom bonded to four different groups).$1.$ $2-$Chloro-$2-$methylbutane: The $C-2$ carbon is bonded to two identical methyl groups,so it is not chiral. Thus,it is optically inactive.$2.$ $3-$Chlorohexane: The $C-3$ carbon is bonded to $-H$,$-Cl$,$-CH_2CH_3$,and $-CH_2CH_2CH_3$. Since all four groups are different,it is chiral and optically active.$3.$ $2-$Chloro-$3-$methylbutane: The $C-2$ carbon is bonded to $-H$,$-Cl$,$-CH_3$,and $-CH(CH_3)_2$. Since all four groups are different,it is chiral and optically active.$4.$ $2-$Chloropentane: The $C-2$ carbon is bonded to $-H$,$-Cl$,$-CH_3$,and $-CH_2CH_2CH_3$. Since all four groups are different,it is chiral and optically active.Therefore,$2-$Chloro-$2-$methylbutane is the optically inactive compound.
