Chemical Bonding › Lewis Structures and Ionic BondsChemical Bonding › Shapes of Molecules and HybridisationChemical Bonding › Molecular Orbitals and Hydrogen BondsChapter 4Chemical Bonding and Molecular Structure
Why is water bent while carbon dioxide is straight? Why is oxygen pulled towards a magnet? The answers lie in how atoms bond. In this chapter you draw Lewis structures, compare ionic and covalent bonds, predict the shapes of molecules with VSEPR theory and hybridisation, and use molecular orbital theory to find bond orders and magnetism. Python counts electrons, predicts shapes and fills molecular orbitals for you to check.

Ionic and Covalent Bonds
The octet rule and Lewis structures, formal charge and its limits, the ionic bond and lattice enthalpy, and the bond length, angle, enthalpy and order that describe any bond.
Shapes of Molecules
VSEPR theory and the shapes it predicts, with lone pairs that squeeze the angles; valence bond theory, sigma and pi bonds; and hybridisation from sp to sp3d2.
