Structural Isomerism (AQA A-Level Chemistry): Flashcards

Molecules with same molecular formula, different arrangements

Atoms connected in different ways

Chain, position, functional group

C atoms arranged differently, different C skeletons

Lower BP, weaker van der Waals forces

Functional group at different positions on C chain

Similar physical, slightly different chemical properties

Same molecular formula, different functional groups

Completely different chemical and physical properties

Ethanol ($-OH$) and dimethyl ether ($C-O-C$)
