Which is an isomer of h c h. The isomer with the methyl groups on the same side is called the cis isomer while the isomer with the groups located on opposite sides is called the trans isomer. Trans isomers of compounds are usually more stable than cis isomers. CH 3 CH 3 C C H H CH 3 CH 3 C C H H cis- 2-butene trans - 2-butene.
