Frequently Asked Questions

Why does carbon form so many compounds?
Carbon's unique ability to form four covalent bonds (tetravalency) and bond with other carbon atoms (catenation) allows it to form long chains, branched chains, and rings, leading to millions of possible compounds.
What's the difference between saturated and unsaturated hydrocarbons?
Saturated hydrocarbons (alkanes) have only single bonds between carbon atoms and are relatively unreactive. Unsaturated hydrocarbons (alkenes and alkynes) contain double or triple bonds and are more reactive.
Why do unsaturated hydrocarbons burn with a sooty flame?
The higher carbon content in unsaturated compounds leads to incomplete combustion, producing unburnt carbon particles that appear as soot, unlike saturated hydrocarbons which burn completely with a clean blue flame.
How does soap clean dirt from clothes?
Soap molecules form micelles with hydrophobic tails attaching to oil/grease and hydrophilic heads facing water. This emulsifies the dirt, allowing it to be rinsed away with water.
What's the difference between ethanol and ethanoic acid?
Ethanol (C2H5OH) is an alcohol - neutral, good solvent. Ethanoic acid (CH3COOH) is a carboxylic acid - sour, acidic. Ethanol can be oxidized to form ethanoic acid.
