Vedclass · Answer

(A) To determine the configuration,assign priorities to the groups attached to each chiral center using Cahn-Ingold-Prelog $(CIP)$ rules.For the top chiral center $(C1)$: The priorities are $-OH$ $(1)$,$-CH(OH)CH_3$ $(2)$,$-CH_3$ $(3)$,and $-H$ $(4)$. Since the lowest priority group $(-H)$ is on a horizontal bond,the configuration is reversed. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is clockwise $(R)$,so it becomes $S$.For the bottom chiral center $(C2)$: The priorities are $-OH$ $(1)$,$-CH(OH)CH_3$ $(2)$,$-CH_3$ $(3)$,and $-H$ $(4)$. Since the lowest priority group $(-H)$ is on a vertical bond,the configuration is maintained. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is counter-clockwise $(S)$,so it remains $S$.Thus,the configuration is $1S, 2S$.
