WebDue to loosely packed molecules, cis isomers have relatively lower melting points than trans isomers. Due to tightly packed molecules, the melting points of trans isomers are usually higher than those of cis isomers. The boiling point of cis isomers is high due to the presence of strong forces of attraction between the atoms of the cis isomer. WebCis-trans isomerism, also known as geometric isomerism, is a type of stereoisomer resulting from double bonds or ring structures. These structures lock the molecule in either the cis or trans form and it cannot …
