Halogenation of alkanes is not a good method of preparation of alkyl halides. Explain. |
|
Answer» Solution :(1) Direct fluorination of alkanes is HIGHLY exothermic, explosive and invariably leads to polyfluorination and decomposition of the alkanes. It is difficult to contrl the reaction. (2) Direct iodination of alkanes is highly REVERSIBLE and difficult to carry out. (3) In direct chlorination and bromination, the reaction is not selective. It can lead to different isomeric monohalogenated alkanes (alkyl halides) as well as POLYHALOGENATED alkanes. Hence, halogenation of alkanes is not a good METHOD of PREPARATION of alkyl halides. |
