What you'll learn
- 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
Here's a simple organic molecule: methane. One carbon atom (C) holds hands with four hydrogen atoms (H). That's it!
- 3
How many hydrogen atoms are attached to the carbon in methane?
- 4
Let's build ethane — two carbon atoms joined together, each with three hydrogens.
- 5
What is the formula for ethane?
- 6
Now build a molecule of propane — 3 carbons in a row, each with enough hydrogens so every carbon has 4 bonds.
- 7
Propane has 3 carbons and how many hydrogens?
