Vedclass · Answer

(A, C) First,determine the configuration of each chiral center using the Cahn-Ingold-Prelog $(CIP)$ priority rules: $1: -OH$,$2: -C_2H_5$,$3: -CH_3$,$4: -H$.For compound $A$: The $-H$ is on a horizontal bond. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is clockwise,so the configuration is $S$.For compound $B$: The $-H$ is on a horizontal bond. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is counter-clockwise,so the configuration is $R$.For compound $C$: The $-H$ is on a horizontal bond. The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is counter-clockwise,so the configuration is $R$.Comparing the configurations: $A$ $(S)$ and $B$ $(R)$ are enantiomers. $B$ $(R)$ and $C$ $(R)$ are identical (they are the same molecule). $A$ $(S)$ and $C$ $(R)$ are enantiomers.Therefore,the correct statements are that $A$ and $B$ are enantiomers,and $A$ and $C$ are enantiomers.

$(I)$ Optical Activity	$(II)$ Form	$(III)$ Sign	$(IV)$ Rotation
$(A)$ Dextrorotatory	$d$	$(+)$	Right
$(B)$ Laevorotatory	$l$	$(-)$	Left
$(C)$ Optically Inactive (Racemic)	$dl$	$(\pm)$	Zero rotation

The correct statement$(s)$ about compounds $A$,$B$,and $C$ is/are:
