Chapter 2: Bonding

Learning Objectives:

• Orbital level understanding of covalent bonding
• Properties of bonds

Summary

We need to deal with the ideas of how atomic orbitals are affected by the formation of covalent bonds. The place to start is with the simplest molecule, a homonuclear diatomic, hydrogen, H₂.

• Covalent bonding in homonuclear diatomics
• Properties of bonds (length, strenght, angles, VSEPR)
  
• Molecular orbitals (wave functions, bonding, anti-bonding, sigma and pi interactions)

• Energy of interacting H atoms
• Combining waves : in-phase and out-of phase
• Molecular orbitals in H₂
• Bonding orbitals
• Anti-bonding orbitals
• Molecular orbitals in He₂

• Interaction of orbitals for H₂ and "He₂"
• Hybridisation :  sp³, sp² and sp
