Hallide

Hallide refers to a class of chemical compounds that are organic molecules containing a halogen atom bonded to a carbon atom. Halogens are elements from Group 17 of the periodic table, including fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Thus, hallides can be fluoroalkanes, chloroalkanes, bromoalkanes, or iodoalkanes, depending on the specific halogen present. They are also known as haloalkanes or alkyl halides.

The properties of hallides vary significantly depending on the type of halogen, the structure of the alkyl group, and the number of halogen atoms present. For example, shorter-chain hallides tend to be volatile liquids, while longer-chain or more highly halogenated compounds can be solids. Their reactivity is also influenced by these factors. Hallides are important intermediates in organic synthesis and find applications in various industries, including as solvents, refrigerants, and in the production of polymers and pharmaceuticals. Some hallides, particularly those with multiple chlorine or bromine atoms, have raised environmental concerns due to their persistence and potential for ozone depletion.
