CONCEPT:

Oxidation and Reduction

  • Oxidation refers to the loss of electrons, increase in oxidation state, or addition of oxygen/removal of hydrogen.
  • Reduction refers to the gain of electrons, decrease in oxidation state, or addition of hydrogen/removal of oxygen.
  • In organic chemistry, oxidation often involves the conversion of alcohols to carbonyl compounds, such as aldehydes or ketones.

EXPLANATION:

  • In the given reaction:

    CH3CH(OH)CH3 → CH3CH(O)CH3 (using chromic acid)

    • The reactant is an alcohol (isopropanol), while the product is a ketone (acetone).
    • This transformation involves the removal of hydrogen (loss of electrons), which is characteristic of an oxidation process.
  • Chromic acid (H2CrO4) is a strong oxidizing agent that facilitates the oxidation of alcohols.
  • In this case, the secondary alcohol (CH3CH(OH)CH3) is oxidized to a ketone (CH3CH(O)CH3).

Therefore, the correct answer is Option 1: Oxidation.
