Organic chemistry fundamentals

What you'll learn

1. 1

   Imagine a box of LEGO bricks. Carbon atoms are like the special 4-stud bricks – they can connect to 4 other bricks!

2. 2

   Here's a methane molecule: one carbon (C) holding hands with four hydrogens (H).

3. 3

   Let's draw the structure of ethane (C₂H₆) together.

4. 4

   Build a molecule of propane (C₃H₈) by connecting carbons and hydrogens.

5. 5

   How many hydrogens does a carbon atom usually bond with?

6. 6

   Here's a double bond – like two handshakes between the same two carbons! Ethene (C₂H₄) has a double bond.

7. 7

   Which molecule has a double bond?
