WebFurthermore, cis-trans geometrical isomerism exists in 2-butene. Cis-2-butene and trans-2-butene are geometrical isomers where trans-2-butene is more stable than cis-2-butene as the former has a lower steric strain. Alkynes: ... melting point and boiling point of alkenes and alkynes increases as the number of carbon atoms present in the ... WebJun 14, 2024 · While providing the reason for the higher melting point of trans molecules, everyone says that trans molecules are more symmetric than cis molecules. An example can be found over here, where the OP states that: trans -2-Butene has more symmetry than its cis isomer which results in better packing and hence higher melting point.
