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. WebGeometric isomers occur in some alkenes.
