H2SO4) & Oxidation 15:10 - Esterification & Saponification (5-Mark Puzzle Questions Solved!) 18:45 - Distinction Tests: Sodium Bicarbonate Test for Ethanoic Acid vs Ethanol 21:30 - Quick-Fire Board Hotspots & Marking Scheme Secrets 🔑 KEY BOARD EXAM FORMULAS & VALUE POINTS COVERED: • Bonding Dilemma: Carbon cannot form C⁴⁺ (excessive energy to remove 4e⁻) or C⁴⁻ (6 protons cannot hold 10e⁻), so it shares electrons to form covalent bonds [1, 2]. • Catenation: Self-linking capability enabled by the small atomic size of carbon, forming exceptionally strong C–C bonds [3, 4]. • Cyclohexane (C₆H₁₂): Contains 18 single bonds (6 C–C and 12 C–H) [5, 6]. • Dehydration Reaction: CH₃CH₂OH → CH₂=CH₂ + H₂O (using hot conc. H₂SO₄ at 443 K as a dehydrating agent) [7-9]. • Esterification: CH₃COOH + C₂H₅OH (Acid Catalyst) → CH₃COOC₂H₅ + H₂O (Sweet-smelling ethyl ethanoate) [10-13]. • Saponification: CH₃COOC₂H₅ + NaOH → CH₃COONa + C₂H₅OH (Used in soap making) [11-13]. • NaHCO₃ Test: Ethanoic acid produces brisk effervescence of CO₂ gas, while ethanol shows no reaction [1, 10, 12, 14]. 📚 FREE RESOURCES: Check out our Class 10 Chemistry Masterclass Slide Deck and Practice Quiz available right here in your Notebook Studio panel! #CBSEClass10 #Class10Science #CarbonAndItsCompounds #ChemistryClass10 #CBSEBoardExam 🏷️ Hashtags #CBSEClass10 #Class10Science #CarbonAndItsCompounds #Class10Chemistry #CBSEBoardExam2026 #ScienceBlueprint #Class10PYQs #NCERTChemistry
