Is alpha-pinene superimposable on its mirror image? Moleculesthat are not superimposable on their miror images rotate the plane of polarized light (optical rotation) if there is more than one mirror image than another in a given sample.
In the model of heptane where the chain is fully extended andanother model been its mirror image . Are these two mirror imagessuperimposable? Should a sample of pure heptane exhibit opticalrotation? Then a model of ethanol and its mirror image---should a sample of pure ethanol exhibit rotation?
