In chemistry, Cis and trans refer to different conformations of a molecule.
For example, the molecule, 1,2-difluoro ethylene can have a cis and trans isomer. In the cis isomer, both fluorine atoms are on the same side of the carbon-carbon bond. In the trans, they are on opposite sides of the carbon-carbon bond axis.
