Organic compounds where a hydrogen atom is replaced by an element from the Halogen family are referred to as halides. This category includes compounds where one or more hydrogen atoms in a hydrocarbon are substituted with halogen atoms, such as fluorine, chlorine, bromine, or iodine. The presence of halogens alters the chemical properties of the original hydrocarbon, allowing for a variety of reactions and behaviors specific to these new compounds.

Alkanes are saturated hydrocarbons that consist only of hydrogen and carbon atoms without any halogen substitution. Amines are organic compounds derived from ammonia, where one or more hydrogen atoms are replaced by an alkyl or aryl group, rather than halogens. Ethers are compounds that contain an oxygen atom bonded to two alkyl or aryl groups, but they do not involve halogen substitution. Therefore, halides specifically denote those compounds that involve the replacement of hydrogen with halogens, making this the correct classification.
