Assertion:Isobutane on oxidation with KMnO_4gives tert-butyl alcohol. Reason:Oxidising agents have no effect on alkanes

Answer»

If both ASSERTION and reason are true and the reason is the CORRECT explanation of the assertion
If both assertion and reason are true butreason is not the correct explanation of the assertion
if assertion is true but reason is false
If the assertion and reason both are false

Solution :Normally oxidising AGENTS have no effect on alkanes. However, alkanes containing a tertiary HYDROGEN atom can be oxidised by oxidising agents such as `KMnO_4` to the corresponding alcohols. For example, `underset"ISOBUTANE"(CH_3-undersetunderset(CH_3)(|)oversetoverset(CH_3)(|)C-H+[O])undersetDeltaoverset("Alkaline " KMnO_4)to underset"tert-butyl alcohol"(CH_3-undersetunderset(CH_3)(|)oversetoverset(CH_3)(|)C-OH)`
