Solution
Alkanes: The general formula for alkanes is CnH2n+2. This means that there are twice as many hydrogen atoms as carbon atoms, plus two additional hydrogen atoms.
Alkynes: The general formula for alkynes is CnH2n-2. This means that there are twice as many hydrogen atoms as carbon atoms, minus two.
