Detailed explanation-1: -Cis-trans isomers exhibit a type of stereoisomerism where the atoms have different spatial arrangements in three-dimensional space. In the field of organic chemistry, cis isomers contain functional groups on the same side of the carbon chain whereas the functional groups are on opposite sides in trans isomers.

Detailed explanation-2: -Cis–trans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space.

Detailed explanation-3: -If the two substituents are on the same side of the double bond, the configuration of the bond is cis. If the two substituents are on opposite sides of the double bond, the configuration of the bond is trans. Created by Jay.

Detailed explanation-4: -The isomer in which the two chlorine (Cl) atoms lie on the same side of the molecule is called the cis isomer (Latin cis, meaning “on this side”) and is named cis-1, 2-dichloroethene.

Detailed explanation-5: -Often, the cis-trans isomers of a compound have different physical properties. These differences can result from different dipole moments in the molecule or different spatial arrangements of the atoms. The boiling point of the cis isomer of pentene is 37°C, while the boiling point of the trans isomer is 36°C.
