Vedclass · Answer

(B) molecule is chiral if it contains at least one chiral carbon atom (a carbon atom bonded to four different groups).$1$. $2-$Bromo-$2-$methylbutane: $CH_3-C(Br)(CH_3)-CH_2-CH_3$. The $C2$ atom is bonded to two identical methyl groups,so it is achiral.$2$. $2-$Bromo-$3-$methylbutane: $CH_3-CH(Br)-CH(CH_3)-CH_3$. The $C2$ atom is bonded to $-H, -Br, -CH_3$,and $-CH(CH_3)_2$. Since all four groups are different,$C2$ is a chiral center. Thus,the molecule is chiral.$3$. $3-$Bromopentane: $CH_3-CH_2-CH(Br)-CH_2-CH_3$. The $C3$ atom is bonded to two identical ethyl groups,so it is achiral.$4$. $2-$Bromopropane: $CH_3-CH(Br)-CH_3$. The $C2$ atom is bonded to two identical methyl groups,so it is achiral.Therefore,the correct option is $B$.
