IB Chemistry SL 2.2.3 Coordination bonds
Practise identifying coordination bonds in ions and molecules, and explaining how a lone pair from one species forms a shared bond to another atom or ion.
How this is tested
- identify coordination bonds in species such as PH4+ and nitric acid
- state that a lone pair donor forms the shared pair in a coordination bond
- distinguish coordination bonding from ionic, metallic and dipole-dipole interactions
