Hypothesis:
1. If butan-1-ol reacts with potassium permanganate then the aldehyde, butanal will be formed because the hydrogen from the carbon attached to the hydroxyl group will bond with the hydrogen from the hydroxyl group, and the oxygen from the oxidizing agent. This would allow the oxygen from the hydroxyl group to form a double bond with the carbon at the end of the chain.
2. If butan-2-ol reacts with potassium permanganate then the ketone, butan-2-one will be formed because the hydrogen atom from the carbon attached to the hydroxyl group will bond with the hydrogen from the hydroxyl
