Question


an unknown dimethylcyclopentane has the formula C7H12 and is optically active. when this compound is hydrogenated, one hydrogen atom adds to one sp2 carbon and another hydrogen atoms adds to the other sp2 carbon, making two isomeric dimethylcyclopentane products. one product is optically active and the other product is inactive. which molecule shown below is the unknown dimethylcyclopentane?

Explanation / Answer

Option B : Hydrogination is cis addition. When it will add to option B two isomers are formed : one meso form (optically inactive) when H2 attacks from the same side of -CH3 and one optically active when H2 attack from the the other side of the plane.
