What are the chemical properties and reactivity of the haloalkane functional group?

Haloalkanes are organic compounds that contain a halogen atom bonded to a carbon atom. They are generally unreactive due to the electronegativity of the halogen atom, which reduces the electron density on the carbon atom. However, they can undergo substitution reactions where the halogen atom is replaced by another group. This reactivity can be influenced by factors such as the type of halogen and the structure of the molecule.
