Experiment 12 — Build a Carbon Compound

Try it in the interactive lab🔊 Audio

Topic: Chemistry · Class 10 · Carbon and its compounds: bonding, chains and isomers

Aim: Build a correct molecule of butane, C₄H₁₀ , with every bond satisfied.

Daily: The LPG in your kitchen cylinder is mostly butane and propane. Carbon’s ability to form four bonds and endless chains is the reason life itself is carbon-based.

Question: How many hydrogen atoms does a saturated hydrocarbon with 4 carbons have?

Exp: CₙH₂ₙ₊₂ = 2 × 4 + 2 = 10.

Question: The valency of carbon is…

Exp: It forms four covalent bonds.

Question: Butane and isobutane are…

Exp: Same formula, different structures.

Question: The functional group in ethanol is…

Question: Soap cleans grease by forming…

Exp: Oil-loving tails surround the grease droplet.
