Edexcel IAL Chemistry AS 7.2 Hydrogen-bond interactions
Edexcel IAL Chemistry AS 7.2 Hydrogen-bond interactions
Show the donor H attached to N, O or F, aim the dotted attraction at a lone pair on another molecule and add the relevant partial charges and angle.
How this is tested
- Draw hydrogen bonds from a lone pair to a δ+ H with the required molecular alignment.
- Explain anomalous HF or NH₃ boiling points by identifying intermolecular hydrogen bonds.
