Answer:
The cis-trans isomerism (or geometric isomerism ) is a type of stereoisomerism of alkenes and cycloalkanes . A distinction is made between the cis isomer , in which the substituents are on the same side of the double bond or on the same face of the cycloalkane. This is an electronic version in English. [ 1 ]
Their characteristics are:
They both have the same formula.They have different chemical and physical properties.The IUPAC advises against the use of the term geometric isomerism. [ 2 ]
