Question:
Which of the following reagent is used for the following reaction ? $CH_3CH_2CH_3 \to CH_3CH_2CHO$
Which of the following reagent is used for the following reaction ? $CH_3CH_2CH_3 \to CH_3CH_2CHO$
Show Hint
To remember alkane oxidation products: Cu $\to$ Alcohol; $Mo_2O_3$ $\to$ Aldehyde; $(CH_3COO)_2Mn$ $\to$ Carboxylic Acid.

- Manganese acetate
- Potassium permanganate
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: This is the controlled oxidation of alkanes.
Step 2: Methane/alkanes oxidized in the presence of Molybdenum oxide ($Mo_2O_3$) yield aldehydes.
Step 3: Specifically, $CH_4 + O_2 \xrightarrow{Mo_2O_3} HCHO + H_2O$. This applies to higher alkanes to form the corresponding aldehyde. *Note: Copper yields alcohols, and Manganese acetate yields carboxylic acids.*
