Question

There are four dimethylcyclopropane isomers

If a mixture consisting of 1 mol of each of these isomers is subjected to simple gas chromatography. Few distinct fractions are obtained. How many of these fractions would be optically active?

• A. 1
• B. 2
• C. 3
• D. None

Answer 1

The correct option is B 2

$\begin{array}{c}\text{When these are subjected to gas chromatography}\\ \text{enantiomers cannot be separated}\\ \text{only the enantiomeric fraction is optically active.}\end{array}$
