van der Waals' strain in cis-1, 2 dimethylcyclopropane is the principal reason for its decreased stability relative to the trans isomer

Cyclohexane gives off more heat per `CH_2` group on being burned in air than any other cycloalkane

The principal source of strain in the boat conformation of cyclohexane is angle strain

The principal source of strain in the gauche conformation of butane is torsional strain
