IB Chemistry SL 2.2.5 Bond polarity
Practise using electronegativity data and Lewis structures to identify bond polarity, classify polar covalent bonds, and assign partial charges correctly.
How this is tested
- use electronegativity difference and average values to identify polar covalent bonds
- deduce which atoms carry δ+ and δ− in molecules such as HCN
- annotate Lewis structures with correct δ+ and δ− symbols on polar bonds
