Vedclass · Answer

(C) For compound $(A)$: Assigning priorities to the groups attached to the chiral center using the Cahn-Ingold-Prelog $(CIP)$ rules: $1$. The $-CH_2-O-CH_2-CH_3$ group attached via the dashed bond is assigned priority $1$. $2$. The oxygen-containing ring carbon is priority $2$. $3$. The $-CH_2-CH_2-O-CH_2-CH_3$ group attached via the wedge bond is priority $3$. $4$. The remaining ring carbon is priority $4$. Following the sequence $1$ $\rightarrow 2$ $\rightarrow 3$ with the lowest priority group $(4)$ on the wedge,the configuration is $S$. For compound $(B)$: Assigning priorities: $1$. The group with the longer chain (heptyl) is priority $1$. $2$. The cyclohexyl group is priority $2$. $3$. The group with the shorter chain (hexyl) is priority $3$. $4$. The methyl group is priority $4$. Following the sequence $1$ $\rightarrow 2$ $\rightarrow 3$ with the lowest priority group $(4)$ in the plane,the configuration is $R$. Thus,the configurations are $S$ and $R$ respectively.

$R$ and $S$ configuration of compound $(A)$ & $(B)$ will be
