Which reagent will you use for the following reaction?
\[\ce{CH3CH2CH2CH3 -> CH3CH2CH2CH2Cl + CH3CH2CHClCH3}\]

उत्तर
Cl2/UV light
Explanation:
Free radical chlorination or bromination of alkanes gives a complex mixture of isomeric mono- and polyhaloalkanes, which is difficult to separate as pure compounds. In this case, a mixture of the two isomeric forms of butane is obtained by the use of Cl2/UV light as per the reaction below -
\[\ce{CH3CH2CH2CH3 ->[Cl2/UV light][or heat] CH3CH2CH2CH2Cl + CH3CH2CHClCH3}\]
