Properties of Haloalkanes

Halogenoalkanes

A halogenoalkane is a halogenated alkane. This means that one (or more) of the hydrogen atoms in an alkane has been replaced by a halogen atom.

Names of halogenoalkanes

The names of halogenoalkanes use the halogen names at the start.
- E.g. Fluoromethane.
- E.g. Chloromethane.
- E.g. Bromomethane.
- E.g. Iodomethane.

Properties of halogenoalkanes

Halogenoalkanes are polar molecules and contain polar bonds.
The polar bonds are important in their reactions.
Because halogens are more electronegative than carbon, the carbon atoms carry a partial positive charge and the halogen atoms carry a partial negative charge.
Halogenoalkanes undergo substitution reactions with ammonia, hydroxide ions, and cyanide ions.

Nucleophiles and electrophiles

A nucleophile is a molecule that is attracted to a nucleus.
- Nuclei have positive charges, so nucleophiles tend to be negatively charged.
- Molecules with lone pairs are also nucleophilic.
An electrophile is a molecule that is attracted to a pair of electrons.
- Electrons have negative charges, so electrophiles tend to be positively charged.
