Vedclass · Answer

(B) compound is optically active if it contains at least one chiral carbon atom (a carbon atom bonded to four different groups).$(1)$ $3-	ext{Bromohexane}$: $CH_3CH_2CH(Br)CH_2CH_2CH_3$. The $C3$ atom is bonded to $-H, -Br, -CH_2CH_3, -CH_2CH_2CH_3$. It is chiral.$(2)$ $2-	ext{Bromo}-2-	ext{methylbutane}$: $CH_3C(Br)(CH_3)CH_2CH_3$. The $C2$ atom is bonded to two identical $-CH_3$ groups. It is achiral.$(3)$ $2-	ext{Bromopentane}$: $CH_3CH(Br)CH_2CH_2CH_3$. The $C2$ atom is bonded to $-H, -Br, -CH_3, -CH_2CH_2CH_3$. It is chiral.$(4)$ $2-	ext{Bromo}-3-	ext{methylbutane}$: $CH_3CH(Br)CH(CH_3)_2$. The $C2$ atom is bonded to $-H, -Br, -CH_3, -CH(CH_3)_2$. It is chiral.Therefore, $2-	ext{Bromo}-2-	ext{methylbutane}$ is not optically active.

Which of the following compounds is $NOT$ optically active?
