Concept:

Isomers:

• These are the compounds that have the same molecular formula but different structures or stereochemistries.
• There is a wide range of classification of organic molecules based on their structures.

Geometrical isomerism:

• Geometrical isomerism is shown in molecules that have a carbon-carbon double bond C = C.
• Geometrical isomerism is shown only when each carbon atom of the double bond is attached to two different atoms or groups.
• Compounds of the type abC = Cad, abC = Cab, and abC = Cde will show geometrical isomerism, where a, b,d, e are alkyl groups.
• The cause of geometrical isomerism is restricted rotation about a C = C bond.

Cis and trans isomerism:

• In a geometrical isomer, if the two identical groups are situated on the same side of the C = C then that is called the cis isomer.
• In a geometrical isomer, if the two identical groups are situated on the opposite side of the C = C then that is called the trans isomer.
• Cis trans isomerism is also shown in cyclic compounds in which two of its ring atoms have different groups attached to its exocyclic single bonds.

Additional Information

• The cis and trans isomers have different physical and chemical properties.
• The trans isomers generally gave higher melting points than the cis ones.
• The dipole moment is greater in the case of cis isomers.
