Alkenes

From stereoisomers to reaction mechanisms and polymerisation, we’ve got you covered 😊.

Stereoisomerism

The Cahn, Ingold, Prelog rules

Understanding how reactions happen

Don’t scroll past this introduction to the terminology of organic reaction mechanisms!

Stabilising carbocations

Inductive and mesomeric effects

Understanding the difference between sigma and pi bonds

If we can explain how it is that carbon can make four bonds by hybridising its 2s and 2p orbitals, we can explain the unique features of single and double bonds in alkenes …
