$3-$Bromopentane

Vedclass · Answer

(D) molecule is chiral if it contains at least one chiral carbon atom,which is a carbon atom bonded to four different groups.$1$. $2-$Hydroxypropanoic acid: $CH_3-CH(OH)-COOH$. The $C-2$ atom is bonded to $-H$,$-OH$,$-CH_3$,and $-COOH$. It is chiral.$2$. $2-$Butanol: $CH_3-CH(OH)-CH_2-CH_3$. The $C-2$ atom is bonded to $-H$,$-OH$,$-CH_3$,and $-CH_2CH_3$. It is chiral.$3$. $2,3-$Dibromopentane: $CH_3-CH(Br)-CH(Br)-CH_2-CH_3$. Both $C-2$ and $C-3$ are bonded to four different groups. It is chiral.$4$. $3-$Bromopentane: $CH_3-CH_2-CH(Br)-CH_2-CH_3$. The $C-3$ atom is bonded to $-H$,$-Br$,and two identical $-CH_2CH_3$ groups. Since it is bonded to two identical groups,it is achiral.Therefore,$3-$Bromopentane is not chiral.
