cis-trans isomerism
Spatial arrangement variation
Cis-trans isomerism is a type of stereoisomerism in chemistry where molecules have the same atoms and bonds but different spatial arrangements around a rigid structure, typically a double bond or ring.
In the cis form, similar groups lie on the same side; in the trans form, they're on opposite sides.
Cis-trans isomerism explains why some fats are solid and others liquid at room temperature.
