| LIST-I Fuel Alcohol | LIST-II Characteristic |
|---|---|
| A. Methanol | I. Mixture of ethanol and gasoline |
| B. Ethanol | II. High energy content |
| C. Gasohol | III. Produced from methane generated by bacterial anaerobic digestion |
| D. Butanol | IV. Can be derived from potato waste |
Answer and explanation
Correct answer D
Biomethanol (CH3OH) can be produced from biogas (methane) generated through the bacterial anaerobic digestion of organic waste (A–III). Bioethanol (C2H5OH) is commonly produced by enzymatic hydrolysis and yeast fermentation of starch-rich agricultural residues such as potato waste (B–IV). Gasohol is a blended motor fuel consisting of a mixture of gasoline and ethanol, typically 90% gasoline and 10% ethanol (C–I). Butanol (C4H9OH), a four-carbon alcohol, has a high energy content (about 29.2 MJ/L, nearly matching gasoline and far exceeding methanol and ethanol) and low water miscibility (D–II).
