How to prepare a halogenoalkane

There are number of ways to make a halogenoalkane, each of which has its own advantages and disadvantages. Halogenation of

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
