Cis-trans isomerism is a form of geometric isomerism that occurs in molecules with a double bond between carbons. The main difference between cis and trans isomers lies in the spatial arrangement of the groups attached to these carbons. In the cis isomer, the similar or identical groups are on the same side of the molecule, in the same plane. In the trans isomer, these groups are on opposite sides, in different planes. The other alternatives are incorrect because they mix concepts of types of bonds with the spatial arrangement of groups, which is not relevant to the definition of cis-trans isomerism.

The cis isomers have four single bonds while the trans have four double bonds.

The cis isomers have two single bonds while the trans have two double bonds.

Cis isomers have the groups attached to the same side of the molecule while trans have the groups attached to opposite sides.

Cis isomers are more volatile than trans.

The cis isomers have the same group attached to both carbons while the trans have different groups attached to each carbon.
