What you'll learn

  1. 1

    Imagine a set of LEGO bricks — different colours, different shapes. Organic chemistry is like playing with a special set where the bricks are carbon atoms! 🧱

  2. 2

    Here's a simple organic molecule: methane. One carbon atom (C) holds hands with four hydrogen atoms (H). That's it!

  3. 3

    How many hydrogen atoms are attached to the carbon in methane?

  4. 4

    Let's build ethane — two carbon atoms joined together, each with three hydrogens.

  5. 5

    What is the formula for ethane?

  6. 6

    Now build a molecule of propane — 3 carbons in a row, each with enough hydrogens so every carbon has 4 bonds.

  7. 7

    Propane has 3 carbons and how many hydrogens?
