Methane is a saturated hydrocarbon. Explain why methane is a hydrocarbon.
Explain why methane is saturated.
Methane reacts with chlorine in the presence of ultraviolet light. State the formulae of two products formed in this reaction.
Draw a dot-and-cross diagram to show the electronic structure of a methane molecule. Include only the outer-shell electrons.
The equation for the complete combustion of methane is given as $\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}$. This reaction is exothermic. Explain, using ideas about bond breaking and bond making, why this reaction is exothermic.
