Hey, future chemist! Are you ready to dive into the exciting world of polymers? 🎉

• In addition polymerization, monomers (small molecules) with double bonds between carbons link up to form a long chain called a polymer.
• Imagine a line of friends holding hands. The monomers are the friends, and when they link hands, they become one big polymer chain.

• Let's look at ethene (C₂H₄), the simplest alkene (hydrocarbon with a double bond).
• When two ethene molecules meet, their double bonds open up and become single bonds, connecting them.
• Think of it as two friends sharing a secret (their double bonds). They open up to each other and become closer, just like ethene molecules form a single bond.
• Now, imagine lots of ethene monomers joining hands, like a big conga line at a party.
• This conga line of ethene monomers is called polyethene!

• We can simplify this polymerization process with a simple equation.
• n represents a huge number of ethene monomers joining together.
• [C₂H₄]n represents polyethene, where n is a large number of ethene monomers linked up.
