Which alcohol is commonly used as fuel?
निम्नलिखित में से कौन-सा अल्कोहल सामान्यतः ईंधन के रूप में प्रयोग किया जाता है?
Detailed Solution & Logic
Ethanol/ इथेनॉल
📘 Explanation
Ethanol is commonly used as a fuel because it burns cleanly and produces less harmful gases compared to petrol or diesel. It is often mixed with petrol (called gasohol or ethanol-blended fuel) to reduce air pollution and dependence on fossil fuels.
Ethanol is produced by fermentation of sugars present in crops like sugarcane, corn, and wheat, making it a renewable fuel.
📗 व्याख्या
इथेनॉल का उपयोग सामान्यतः ईंधन के रूप में किया जाता है क्योंकि यह स्वच्छ रूप से जलता है और पेट्रोल-डीजल की तुलना में कम हानिकारक गैसें उत्पन्न करता है। इसे पेट्रोल में मिलाकर (एथेनॉल मिश्रित ईंधन) वायु प्रदूषण कम किया जाता है और जीवाश्म ईंधनों पर निर्भरता घटाई जाती है।
इथेनॉल गन्ना, मक्का और गेहूँ जैसी फसलों में मौजूद शर्करा के किण्वन (fermentation) से बनाया जाता है, इसलिए यह नवीकरणीय ईंधन है।
⭐ Extra Facts / अतिरिक्त तथ्य
🔹 Ethanol is called biofuel because it is made from plants.
🔹 भारत में E20 fuel (20% ethanol + 80% petrol) को बढ़ावा दिया जा रहा है।
🔹 Methanol can also be used as fuel, but it is more toxic than ethanol.
🔹 Ethanol combustion produces mainly carbon dioxide and water, so it is relatively eco-friendly.
