WebApr 6, 2024 · isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. The roots of the word isomer are Greek—isos plus meros, or “equal parts.” Stated colloquially, isomers are chemical compounds that have the same parts but are … WebAs such cis-but-2-ene should have stronger intermolecular forces than trans-but-2-ene causing cis-but-2-ene to have a higher boiling point. However you seem to have their boiling points mixed up. Cis-but-2-ene has a boiling point of 4°C and trans-but-2-ene has a boiling point of 1°C. Hope that helps.
