Alkanes, while stable and largely unreactive, can undergo radical reactions, particularly with halogens, transforming into alkyl halides. Position isomers are also coming under the structural isomers. This process involves three key steps: initiation, where radicals are generated; propagation, where radicals react with alkanes to form new radicals and alkyl halides; and termination, where radicals combine to form stable products. 2: This is known as the "chair" form of cyclohexane from its shape, which vaguely resembles a chair.
