Douglas Lin · Answer 1

The two possible enantiomers for the starting material and the products are shown below,

Where;

J = (S) - 1,4-dimethylcyclobut-1-ene

Or,

J = (R) - 1,4-dimethylcyclobut-1-ene

And,

K = 1,2-dimethylcyclobutane

Both enantiomers have same molecular formula (C₆H₁₀) but different stereochemistry about chiral carbon.

Upon catalytic hydrogenation two hydrogen atoms are added across double bond resulting in the formation of cyclobutane.
