Alkanes, as saturated hydrocarbons, are primarily used as fuels due to their high energy content. They are also key in producing lubricants, plastics, and pharmaceuticals. Halogenation enhances alkane reactivity, creating halogenoalkanes, which are vital intermediates in organic synthesis. The free radical substitution mechanism, including initiation, propagation, and termination stages, is central to this transformation. Despite challenges in reaction control, advancements aim to refine halogenation for industrial applications.

Alkanes are saturated hydrocarbons with single bonds between carbon atoms, including methane, ethane, propane, and butane
Fuels
Alkanes are valued for their high energy content and are commonly used as fuels
Production of Lubricants, Plastics, and Pharmaceuticals
Alkanes are also utilized in the production of various products such as lubricants, plastics, and pharmaceuticals
Starting Material for Chemical Syntheses
Alkanes serve as a starting material for various chemical syntheses
Despite their chemical inertness, alkanes can undergo reactions under specific conditions, such as halogenation, which increases their reactivity for further chemical transformations
Halogenation is a process that introduces halogen atoms into the hydrocarbon chain, yielding halogenoalkanes
Initiation
The free radical substitution mechanism begins with the homolytic cleavage of a halogen molecule, often induced by UV light
Propagation
During propagation, halogen radicals react with alkanes, successively replacing hydrogen atoms with halogen atoms
Termination
The process concludes with termination, where radicals combine to form stable, non-radical products, halting the reaction
Halogenation of alkanes can produce more reactive molecules, but the lack of selectivity can limit its industrial applicability

Definition of Alkanes
Alkanes are saturated hydrocarbons with only single bonds between carbon atoms.
01
Combustion of Alkanes
Alkanes combust exothermically, releasing heat and light, used primarily as fuels.
02
Cracking Process
Cracking converts long-chain alkanes into shorter, more reactive hydrocarbons like alkenes.
