However, it is easy to find examples where the cis-trans system is not easily applied. IUPAC has a more complete system for naming alkene isomers.

WebHowever cis-2-butene does not spontaneously convert into trans-2-butene at normal conditions, instead they exist as mixture. There are various isomerization reactions which can convert one isomer into another, but they usually require nonstandard conditions and/or the addition of a catalyst of some kind.
