Topics covered in Isomerism for JEE Advanced Chemistry.
Topics in Isomerism
1
Classification of Isomerism
- Isomers have the same molecular formula but different structural or spatial arrangements
- Two main types: Structural (Constitutional) and Stereoisomerism
- Structural isomerism includes chain, position, functional, metameric, tautomeric, and ring-chain
2
Chain (Nuclear) Isomerism
- Isomers differ in the arrangement of carbon chain skeleton
- Same molecular formula but different carbon frameworks
- Properties: Different physical properties but similar chemical properties
3
Position Isomerism
- Isomers differ in the position of functional group or multiple bond
- Same carbon skeleton but different functional group locations
- Examples: But-1-ene vs But-2-ene, Propan-1-ol vs Propan-2-ol
4
Functional Isomerism
- Isomers have same molecular formula but different functional groups
- Different chemical and physical properties due to different functional groups
- Common pairs: alcohols-ethers, aldehydes-ketones, carboxylic acids-esters
