- Sugarcane plants are one of the most efficient convertors of sunlight into chemical energy.
- Sugarcane juice is used to prepare molasses which is fermented to give alcohol (ethanol). Some countries now use alcohol as an additive in petrol since it is a cleaner fuel which gives rise to only carbon dioxide and water on burning in sufficient air (oxygen).
- As the Alcohol molecule contains oxygen, it allows the engine to more completely combust the fuel, resulting in fewer emissions and thereby reducing the occurrence of environmental pollution. Since alcohol is produced from plants that harness the power of the sun, it is also considered as renewable fuel.

With reference to alcohol, consider the following statements: 1. Suga...
Explanation:
Sugarcane juice can be used to prepare molasses which is fermented to give alcohol (ethanol)
- This statement is correct. Sugarcane juice is rich in sucrose, and it can be used as a raw material for the production of alcohol. The juice is extracted from the sugarcane plant, and it undergoes a process of fermentation to convert the sugars into alcohol. During fermentation, yeast is added to the juice, which converts the sugars into ethanol and carbon dioxide. The resulting product is molasses, which can be further distilled to obtain alcohol.
Alcohol can be used as an additive in petrol since it is a cleaner fuel
- This statement is also correct. Alcohol, particularly ethanol, can be used as an additive in petrol to enhance its properties. Ethanol is a cleaner-burning fuel compared to gasoline, as it produces fewer emissions of harmful pollutants such as carbon monoxide and particulate matter. It also has a higher octane rating, which improves the performance of the engine. In some countries, ethanol is blended with petrol in various proportions, such as E10 (10% ethanol and 90% petrol) or E85 (85% ethanol and 15% petrol), to create a more environmentally friendly fuel.
Conclusion
- Both statements are correct. Sugarcane juice can be used to produce molasses, which is fermented to obtain alcohol (ethanol). Alcohol, particularly ethanol, can be used as an additive in petrol to improve its properties and reduce emissions.
