Vedclass · Answer

(A) meso compound is optically inactive due to the presence of a plane of symmetry or center of inversion. For $2,3$-butanediol,the meso form has a plane of symmetry in its eclipsed conformation. By analyzing the given Newman projections: In structure $P$,the groups are arranged such that there is a plane of symmetry passing through the molecule,making it the meso form. In structure $Q$,the arrangement also allows for a plane of symmetry,representing another conformation of the meso form. Structures $R$ and $S$ do not possess the required symmetry for the meso form of $2,3$-butanediol. Therefore,$P$ and $Q$ are the Newman projections of meso-$2,3$-butanediol.

Column-$I$	Column-$II$
$A$. Acetaldehyde,vinyl alcohol	$1$. Enantiomers
$B$. Eclipsed and staggered ethane	$2$. Tautomers
$C$. $(+)$$2$-butanol,$(-)$$2$-butanol	$3$. Chain isomers
$D$. Methyl-$n$-propylamine and diethylamine	$4$. Conformational isomers
	$5$. Metamers

Among the following,the Newman projections of meso-$2,3$-butanediol are
