Which of the following reagent is used for the following reaction? CH 3 CH 2 CH 3   → ? CH 3 CH 2 CHO  

Options

  1. ACopper at high temperature and pressure
  2. BManganese acetate
  3. CMolybdenum oxide
  4. DPotassium permanganate

Correct answer

C. Molybdenum oxide

Step-by-step solution

CH 3 - CH 2 - CH 3   → Mo 2 O 3 CH 3 - CH 2 - CH = O   The reagent used will be Mo 2 O 3 (molybdenum oxide) as this reagent always used to oxidise alkanes to aldehyde. So, it is widely used as an oxidation catalyst for acid-mediated catalytic reactions.
