Deduce the structure of each compound from the information given. All unknowns in this problem have the molecular formula C8H12
A) Upon catalytic hydrogenation, unknown X gives cyclooctane. Ozonolysis of X, followed by reduction with dimethyl sulfide, gives octanedioic acid. Draw the structure of X
B) Upon Catalytichydrogenation, unknown Y gives cyclooctane. Ozonolysis of Y, followed by reduction with dimethyl sulfide, gives to equivalents of butanedial. Draw the structure of Y.
C) upon catalytic hydrogenation unknown Z gives cyclooctane. Oxonolysis of Z followed by reduction with dimethyl sulfide, gives a three0carbon dialdehyde and a five-carbon dialdehyde. Draw the stucture of Z.
