How many bonds do alkynes have
WebThe CnH2n-2 Rule. This rule can be proven by looking at the structures of common monounsaturated alkenes, such as ethene (C2H4) and propene (C3H6), which have twice the number of hydrogens as they do carbons. The general formula becomes more complicated for polyunsaturated alkenes with more than one double bond.
