Cis- isomer

WebThe cis isomer is more stable than the trans isomer by approximately 40 kJ mole − 1. With an increasing number of CH₂ groups to span the two carbon atoms of the double bond, the strain of the trans isomer becomes less severe. For example, the isomeric cyclododecenes are of comparable stability.

WebA cis isomer has two substituents on the same face of the ring. A trans isomer has one "up" substituent and one "down" substituent. -1,4-dichlorocyclohexane can adopt a conformation with both of its substituents in equatorial positions, while an axial, equatorial conformation is the only possibility for -1,4-dichlorocyclohexane. WebCis and trans isomers are types of geometric isomers, where the functional group is placed differently with regards to the double bond. In general, a cis isomer has molecules on one side of the double bond. A trans isomer has molecules on the other side of the double bond. Spot the differences in the the example below:
