2-Methylbutanal, upon reduction with hydrazine and KOH, produces:
Correct answer: B. Pentane
- A. Butane
- B. Pentane
- C. Isobutanol
- D. Isopentanol
Explanation
Pentane (n-pentane) is an alkane with the molecular formula C5H12. It has a straight-chain structure with no branching or substituents on the carbon backbone.Therefore, the correct answer is "b) Pentane" as the product resulting from the reduction of 2-methylbutanal with hydrazine and KOH.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
