Understanding Stereoisomerism
Stereoisomerism is a form of isomerism where compounds have the same molecular formula and connectivity of atoms but differ in the spatial arrangement of atoms. Among the options provided, the pair that represents stereoisomerism is optical isomerism and geometrical isomerism.
Types of Stereoisomerism
- Optical Isomerism:
- Involves isomers that are non-superimposable mirror images of each other.
- Often occurs in chiral molecules, where a carbon atom is attached to four different groups.
- Example: Lactic acid exists in two forms, D-lactic and L-lactic, which rotate plane-polarized light in opposite directions.
- Geometrical Isomerism
- Also known as cis-trans isomerism, it arises due to restricted rotation around a double bond or a ring structure.
- Isomers differ in the spatial arrangement of groups attached to the carbon atoms involved in the double bond.
- Example: In but-2-ene, the cis-isomer has both methyl groups on the same side, while the trans-isomer has them on opposite sides.
Why Other Options Do Not Represent Stereoisomerism
- Option A: Structural isomerism and geometrical isomerism
- Structural isomerism involves different connectivity of atoms, not just spatial arrangement.
- Option C: Chain isomerism and rotational isomerism
- Chain isomerism differs in the carbon skeleton, while rotational isomerism relates to conformers, not stereoisomers.
- Option D: Linkage isomerism and geometrical isomerism
- Linkage isomerism involves different connections of ligands to a central atom, which does not pertain to spatial arrangement.
In summary, optical isomerism and geometrical isomerism are both forms of stereoisomerism, making option B the correct answer.
