This is the second modern theory of bonding, the first being valence bond theory. In molecular orbital theory covalent bonds
Our familiar model of covalent bonding is largely based on the Lewis model, with atoms sharing pairs of bonding electrons

Mass spectrometry is a really powerful tool for helping us to piece together the structure of an organic molecule. Ionisation

Halogenoalkanes undergo substitution reactions in the presence of a nucleophile such as the hydroxide ion, OH–, but most good nucleophiles
Can we predict the trend in reactivity of fluoromethane, chloromethane, bromomethane and iodomethane based on any of the information below?

Halogenoalkanes react with nucleophiles in nucleophilic substitution reactions. The halogen atom in the molecule is replaced by the nucleophile and
