Vedclass · Answer

(C) $1$. Assign priorities to the groups attached to each chiral center ($C-2$ and $C-3$) using Cahn-Ingold-Prelog $(CIP)$ rules.$2$. For $C-2$: The groups are $-Cl$ (priority $1$),$-CH(Cl)C_2H_5$ (priority $2$),$-CH_3$ (priority $3$),and $-H$ (priority $4$). The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is counter-clockwise. Since the lowest priority group $(-H)$ is on the horizontal axis,the configuration is $S$.$3$. For $C-3$: The groups are $-Cl$ (priority $1$),$-CH(Cl)CH_3$ (priority $2$),$-C_2H_5$ (priority $3$),and $-H$ (priority $4$). The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is counter-clockwise. Since the lowest priority group $(-H)$ is on the horizontal axis,the configuration is $S$.$4$. Therefore,the configuration is $2S, 3S$.
