Vedclass · Answer

(D) To determine the absolute configuration,we use the $CIP$ (Cahn-Ingold-Prelog) priority rules.For the first compound:The priorities are: $1: -CH_2SH$,$2: -CH_2OH$,$3: -CH_3$,$4: -H$.The lowest priority group $(-H)$ is on a wedge. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ appears clockwise,but since the lowest priority group is on a wedge,the configuration is inverted to $S$.For the second compound:The priorities are: $1: -OH$,$2: -CH_2SH$,$3: -CH_3$,$4: -H$.The lowest priority group $(-H)$ is on a dash. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ appears clockwise,which corresponds to $R$ configuration.Thus,the configurations are $S$ and $R$ respectively.

The absolute configurations of the following compounds are respectively:
