Isomers definition

Compounds with same molecular formula but different properties

Structural isomerism definition

Same molecular formula, different atom arrangements

3 types of structural isomerism

Chain, positional, functional group

Chain isomerism definition

Different carbon skeleton arrangements (straight vs branched)

Positional isomerism definition

Functional group at different positions on same carbon chain

Functional group isomerism definition

Different functional groups, different homologous series

Functional group isomers: C3H6O\text{C}_3\text{H}_6\text{O}

Propanal (aldehyde) and propanone (ketone)

Oxidation of aldehydes vs ketones

Aldehydes easily oxidized; ketones resistant to oxidation

BP: butane vs 2-methylpropane

Butane higher (larger surface area for intermolecular forces)

Linalool vs geraniol smell

Linalool: lavender; geraniol: roses
