(2 points) A substance conducts electricity in the solid and molten state. Valence electrons of Mg atoms are free to move throughout the structure. This volume presents compilations and critical evaluations of reported solubility data for the title compounds published up to mid-1984. Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds.

Surprisingly, their cyclohexanes boiled higher by 10 °C than either hexahydrobenzene or hexanaphtene, but this riddle was solved in 1895 by Markovnikov, N.M. Kishner, and Nikolay Zelinsky when they reassigned "hexahydrobenzene" and "hexanaphtene" as methylcyclopentane, the result of an unexpected rearrangement reaction.
