Consider the following substances:
I. Ethanol
II. Nitroglycerine
III. Urea
Coal gasification technology can be used in the production of how many of them?
(a) Only one
(b) Only two
(c) All the three
(d) None
Answer: (b) Only two
Explanation:
Ethanol – Yes, coal gasification produces syngas (CO + H₂), which can be used to synthesize ethanol via fermentation or chemical routes.
Nitroglycerine – No, coal gasification is not used in its synthesis; nitroglycerine is made from glycerol and nitric acid, not from coal-derived products.
Urea – Yes, coal gasification provides ammonia (via syngas → NH₃), which combines with CO₂ to produce urea.
