Given below are two statements:

Statement-I : 22 -methylbutane on oxidation with KMnO4{KMnO}_{4} gives 22 -methylbutan-22-ol.

Statement-II : nn -alkanes can be easily oxidised to corresponding alcohol with KMnO4{KMnO}_{4}.

Choose the correct option :

Given below are two statements: Statement-I : 2 -methylbutane on oxidation with KMnO _ 4 gives 2 -methylbutan- 2 -ol.

Options

  1. ABoth statement I and statement II are correct
  2. BBoth statement I and statement II are incorrect
  3. CStatement I is correct but Statement II is incorrect
  4. DStatement I is incorrect but Statement II is correct

Correct answer

C. Statement I is correct but Statement II is incorrect

Step-by-step solution

Alkanes are very less reactive, tertiary hydrogen can oxidise to alcohol with KMnO4{KMnO}_{4}.

Given below are two statements: Statement-I : 2 -methylbutane on oxidation with KMnO _ 4 gives 2 -methylbutan- 2 -ol.
