**One-Shot | 10th Chemistry Chapter 23 Monohydroxy Alkanes or Alcohols | New Book 2026 | Full Chapter Long & Short Questions Complete Guide** Welcome to this comprehensive **One-Shot Masterclass** on **10th Class Chemistry Chapter 23: Monohydroxy Alkanes or Alcohols**, strictly based on the **PECTAA New Book Syllabus for 2026**! Whether preparing for annual board exams or strengthening organic chemistry concepts, this complete video covers all key concepts, balanced chemical equations, industrial preparation methods, and exercise questions in clear, easy-to-understand Urdu/Hindi. --- ### 📌 What You Will Learn in This Video: * **1. Fermentation of Glucose by Yeast (Ethanol Manufacture):** * Definition of fermentation and everyday examples (yogurt, bread, alcohol) * Essential reaction conditions: Yeast enzymes, optimum temperature (~35°C), neutral/acidic pH, and anaerobic environment * Balanced reaction: $\text{C}_6\text{H}_{12}\text{O}_6 \xrightarrow{\text{Yeast, } 35^\circ\text{C}} 2\text{C}_2\text{H}_5\text{OH} + 2\text{CO}_2$ * Why oxygen must be excluded (preventing oxidation to ethanoic acid) and yeast toxicity above 15% ethanol concentration * **2. Hydration of Ethene (Industrial Preparation of Ethanol):** * Addition reaction mechanism of water across the carbon-carbon double bond * Catalytic conditions: Steam over concentrated phosphoric acid ($\text{H}_3\text{PO}_4$) at $300^\circ\text{C}$ and $60\text{ atm}$ pressure * Condensation into liquid ethanol and key industrial applications * **3. Comparison: Hydration of Ethene vs. Fermentation:** * Operating temperatures and pressures * Raw materials (crude oil/petrochemical vs. renewable cane sugar) * Speed/rate of reaction, purity levels, energy costs, and production economy * **4. Combustion of Alcohols & Heat of Combustion:** * * **5. Applications of Alcohols as Fuels:** * Usage of aliphatic alcohols ($\text{C}_1$ to $\text{C}_4$) in internal combustion engines * Advantages (renewable source, zero sulfur oxides, high efficiency) * Disadvantages (lower energy density per volume, engine component wear, food crop competition) * The carbon-neutral cycle of bio-alcohols * **6. Industrial Roles, Daily Life Importance & Hazards:** * **Pharmaceutical Industry:** Active solvent, preservative, hand sanitizers, and disinfectant * **Cosmetics Industry:** Volatility, deodorizing, antimicrobial, and refreshing properties in perfumes and skin lotions * Everyday antiseptic uses (methylated spirit, snakebite antidotes) vs. harmful health hazards and alcohol toxicity * **Exercise Short & Long Questions:** Direct exam-oriented answers and board marking tips. ### 🎯 Specially Prepared For: * Punjab Board Students (Lahore, Rawalpindi, Faisalabad, Gujranwala, Multan, Sahiwal, Bahawalpur, Sargodha, DG Khan, AJK) * PECTAA New Chemistry Curriculum 2026 * Matric / SSC Part 2 Students * Federal Board & Other Boards following the updated National Curriculum --- ### 🔍 Related Searches & Keywords: class 10 chemistry chapter 23, chapter 23 monohydroxy alkanes or alcohols, 10th chemistry unit 23 new book 2026, fermentation of glucose by yeast class 10, hydration of ethene ethanol preparation, combustion of alcohols class 10 chemistry, alcohols as fuel advantages and disadvantages, uses of ethanol in pharmaceutical and cosmetic industries, class 10 chemistry new syllabus 2026, pectaa chemistry syllabus 2026, matric chemistry chapter 23 one shot, punjab board chemistry class 10 chapter 23, 10th class chemistry lecture urdu hindi, exercise short questions unit 23 chemistry 10th. --- ### 🏷️ Relevant Hashtags: #PECTAA #10thClass #PunjabBoard #10thChemistry #ChemistryNewBook #ChemistryNewBook2026 #MonohydroxyAlkanes #AlcoholsClass10 #MatricChemistry #Class10Chemistry #ScienceEducation #ChemistryLecture #SSC2Chemistry #BoardExam2026
