Trans is a Latin word meaning "on the opposite side" and is the opposite of cis, which means "on the same side".
- In chemistry, a bond not subject to free rotation in which the greater radical on both ends is on the opposite side of the bond is called trans. Compare with cis.
- In the diagram on the right, the hydrogen atoms are on opposite sides of the double bond. They cannot rotate to the same side of the molecule, as (unlike with a single bond) double bonds prevent this from happening.
