Electronic structure and orbitals . . .
An introduction to the arrangement of electrons in atoms - leading to the modern electronic structures of carbon and hydrogen.
Bonding in methane . . .
Covers bonding in methane and ethane, including a simple look at hybridisation.
Bonding in ethene . . .
Covers bonding in ethene, including a simple look at hybridisation.
Bonding in ethyne (acetylene). . .
Looks at the formation of a carbon-carbon triple bond. (If you aren't happy about bonding in ethene, read that first!)
Bonding in benzene - the Kekulé structure . . .
A description of the Kekulé structure for benzene and the reasons (including hydrogenation energies) why it isn't satisfactory.
Bonding in benzene - a modern orbital view . . .
Covers a modern view of the bonding in benzene, including a simple look at hybridisation.
Bonding in carbonyl compounds . . .
Describes the carbon-oxygen double bond in methanal (including a simple look at hybridisation), but applies equally to other aldehydes and ketones like ethanal and propanone.
Electronegativity . . .
An introduction to electronegativity as it applies to organic chemistry, including its causes. Bond polarity.
