Chapter 8, Problem 55P

A mixture of three alkenes (A, B, and C) was obtained by dehydration of $\text{1,2-dimethylcyclohexanol}$. The composition of the mixture was A ( $3\%$), B ( $31\%$), and C ( $66\%$). Catalytic hydrogenation of A, B, or C gave $\text{1,2-dimethylcyclohexane}$. The three alkenes can be equilibrated by heating with sulfuric acid to give a mixture containing A ( $0\%$), B ( $15\%$), and C( $85\%$). Identify A, B, and C.
