(D) The structure of $2$-Bromo-$3,4,5$-trimethylhexane is $CH_3-CH(Br)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH_3$.Identify the chiral carbons (carbons attached to four different groups):$(1)$ $C_2$: Attached to $-H$, $-Br$, $-CH_3$, and $-CH(CH_3)CH(CH_3)CH_2CH_3$. This is chiral.$(2)$ $C_3$: Attached to $-H$, $-CH_3$, $-CH(Br)CH_3$, and $-CH(CH_3)CH_2CH_3$. This is chiral.$(3)$ $C_4$: Attached to $-H$, $-CH_3$, $-CH(CH_3)CH(Br)CH_3$, and $-CH_2CH_3$. This is chiral.$(4)$ $C_5$: Attached to $-H$, $-CH_3$, $-CH_2CH_3$, and $-CH(CH_3)CH(CH_3)CH(Br)CH_3$. This is chiral.All four carbons at positions $2, 3, 4,$ and $5$ are chiral.Therefore, the total number of chiral carbon atoms is $4$.
