TRANS

pref. over, across, beyond

Trans is a Latin noun or prefix, meaning "across", "beyond" or "on the opposite side [of]" . It is the opposite of cis, which means "on the same side [of]".In chemistry, a double bond (or ring) not subject to free rotation in which the greater radical on both ends is on the opposite side of the bond (or face of the ring) is called trans. Compare with cis. In the diagram on the right, the hydrogen atoms are on opposite sides of the carbon chain. They cannot rotate to the same side of the molecule, as (unlike with a single bond) double bonds prevent this from happening. A similar phenomenon is seen in cyclic compounds (in which the atoms form a closed ring), where substituents can be on the same "face" of the ring (cis) or opposite faces (trans.)See geometric isomerism for more on this topic.
