NCERT Activity 4.1: Watch atoms share electrons to form covalent bonds. See H₂, Cl₂, and CH₄ form step by step and understand why carbon compounds have low melting points.
NCERT Activity 4.2: Explore catenation — carbon's unique ability to form straight chains, branched chains, and rings. Discover why carbon forms millions of compounds.
NCERT Activity 4.3: Compare ethane, ethene, and ethyne. Test with bromine water — unsaturated compounds decolorize it, saturated ones don't!
NCERT Activity 4.4: Burn candle wax, LPG, and acetylene. Observe yellow vs blue flames and test for CO₂ with lime water. Complete vs incomplete combustion!
NCERT Activity 4.5: Investigate ethanol — smell, water solubility, reaction with sodium (H₂ gas), and dehydration with conc. H₂SO₄ to produce ethene.
NCERT Activity 4.6: Test ethanoic acid — vinegar smell, litmus turns red, CO₂ with NaHCO₃, and sweet-smelling ester formation with ethanol.
NCERT Activity 4.7: Prepare soap from oil + NaOH (saponification), add salt to precipitate it, then compare soap vs detergent in hard water!
