Shapes of organic molecules; σ and π bonds
What this topic asks you to be able to do
- describe any organic molecule as one of three types: straight-chained, branched or cyclic
- describe and explain the shape taken by molecules made up of sp, sp2 and sp3 hybridised atoms, together with the bond angles present in them
- outline how σ and π bonds are positioned within molecules that include sp, sp2 and sp3 hybridised atoms
- understand and apply the word planar when describing how atoms are arranged in organic molecules, for example ethene
