Pearson Edexcel IAL Chemistry AS 3.14 Bonding continuum & polarity
Pearson Edexcel IAL Chemistry AS 3.14 Bonding continuum & polarity
Practise using electronegativity differences, dipoles and electron-density evidence to place bonds on the ionic-covalent continuum.
How this is tested
- use electronegativity data to compare ionic and covalent character in chlorides
- explain bond polarity by assigning δ+ and δ- from the more electronegative atom
- interpret dipole or electron-density diagrams for polar covalent bonds
