Question

What is the common name of halo alkane?

Answer 1

Hint : The replacement of hydrogen atoms in an aliphatic hydrocarbon by halogen atoms results in the formation of haloalkanes. In haloalkanes, the halogen atom is attached to the $s{p^3}$ hybridized carbon atom of an alkyl group.

Complete Step By Step Answer:
The common name of haloalkane is alkyl halide. In haloalkanes, the halogen atom is bonded to an alkyl group. So, they form a homologous series represented by the formula ${C_n}{H_{2n + 1}}X$ . Alkyl halides are further classified as primary, secondary or tertiary according to the nature of the carbon atom to which the halogen is attached. The polarity of the carbon-halogen bond of the haloalkanes is responsible for their nucleophilic elimination, nucleophilic substitution and reaction with metal atoms to form organometallic compounds. Alkyl halides can be classified as mono, di or polyhalogen compounds depending on the number of halogen atoms present in their structures. Alkyl halides are organic compounds which can dissolve non-polar compounds. So, they are used as solvents. Many derivatives of alkyl halides are used in medicines. Alkyl halides are also called halogenoalkanes.
Therefore, the common name of halo alkane is alkyl halide.

Note :
The properties of alkyl halides are similar to those of parent alkanes in being colorless, relatively odorless and hydrophobic. Alkyl halides are less flammable than alkanes as they contain less carbon-hydrogen bonds. So, some alkyl halides are used in fire extinguishers. Remember that the formal naming of haloalkanes should follow IUPAC nomenclature and the halogen is the prefix to the alkane.
