Question

Assertion:Isobutane on oxidation with `KMnO_4` gives tert-butyl alcohol.
Reason:Oxidising agents have no effect on alkanes
A. If both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. if assertion is true but reason is false
D. If the assertion and reason both are false

Answer 1

Correct Answer - B
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)`
