Which of the following compounds will give butanone on oxidation with alkaline KMnO4

solution?

1.  Butan-1-o1                 
2. Butan-2-ol
3.  Both (a) and (b)             
4.  None of the above

Hint: KMnO4 is an oxidising agent

Butan-2-ol on oxidation with alkaline KMnO4 solution produces butanone as follows:

It is an example of oxidation reaction.
