Question

preparation of haloalkanes from alkanes by free radical halogenation

Answer 1

Explanation:

For preparation of haloalkanes from alkanes is a simple process also called halogenation of alkanes.It means when we react a alkane with any halogen X

then we obtain haloalkane. This process is mainly endothermic.Or requires uv for completion of reaction.

example.

CH4+Br2 ---Uv----> CH3Br+H.freeradical

Answer 2

Answer:

CH3CH2CH2CH3 ----Cl2/UV LIGHT OR HEAT---> CH3CH2CH2CH2Cl + CH3CH2CHclCH3

Explanation:

-> chorination or bromination of alkanes gives a complex mixture of iso monomeric and polyhaloalkanes as pure seperate compounds

-> yeild of single compound is low
