Organic Chem.
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
Cracking breaks long, low-demand hydrocarbon chains into shorter, more useful ones using heat and a catalyst. It produces both alkanes for fuel and alkenes for polymer manufacture, matching what a refinery makes to what the market actually wants.
Key Words
Tap a word to see its definition.
Steps
Read the explanation above and note the two key terms before you start.
Balance three cracking equations, each producing one alkane and one alkene from a long-chain starting material. Then explain, using supply and demand, why refineries crack rather than sell the long fractions.
Record what actually happened, including anything that did not match what you expected.
Write a conclusion that answers the question this lesson opened with, and state your uncertainty.
