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. WebSo these are both, these are both situations, there are both stereoisomers, stereoisomers, and this particular variation of stereoisomer is called a cis trans isomer.

Cis- isomer

WebCis and trans isomers are types of geometric isomers, where the functional group is placed differently with regards to the double bond. In general, a cis isomer has molecules on one side of the double bond. A trans isomer has molecules on the other side of the double bond. Spot the differences in the the example below: WebThe cis -isomer is much more stable; [3] the ring-strain energies being 16.7 and 7.4 kcal/mol, respectively. [4] A planar arrangement of the ring carbons would be too strained, and therefore the stable conformations of the trans form have a bent (non-planar) ring.
