The exam pushed students on their knowledge of isomers for ethane and ethene derivatives. Unlike modern exams, which might ask for the effect of a functional group on boiling point, the 1972 answers required hand-drawing every possible geometric and structural isomer resulting from substituting chlorine and bromine atoms into hydrocarbons.
