Vedclass · Answer

(D) For $1,2-$dimethylcyclopropane,there are two chiral centers at $C1$ and $C2$.$1,2-$dimethylcyclopropane exists in three stereoisomeric forms:$1$. $cis-1,2-$dimethylcyclopropane: This molecule has a plane of symmetry and is achiral (meso compound).$2$. $trans-1,2-$dimethylcyclopropane: This exists as a pair of enantiomers (dextrorotatory and levorotatory forms).Thus,there are a total of $3$ stereoisomers ($1$ meso form + $2$ enantiomers).

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

The number of stereoisomers possible for $1,2-$dimethylcyclopropane is:
