⛓️ The Simplest Carbon Family
Carbon is special. It can bond to four other atoms at once, and it loves bonding to other carbon atoms. This lets it form chains — short chains, long chains, branched chains, rings...
The alkanes are the simplest family of carbon compounds. They're like the "basic" hydrocarbons — just carbon and hydrogen, with only single bonds. Methane (natural gas), propane (BBQ gas), and petrol are all alkanes!
Alkanes are like a chain of people holding hands! Each carbon (person) can hold hands with 4 others. In a chain, they hold two carbons and fill the rest with hydrogens. The longer the chain, the stronger the intermolecular forces — that's why longer alkanes have higher boiling points (they "stick together" more)!
