Answer» Answer: As noted before, alkenes are HYDROCARBONS with carbon-to-carbon DOUBLE bonds (R2C=CR2) and alkynes are hydrocarbons with carbon-to-carbon triple bonds (R–C≡C–R). Collectively, they are called unsaturated hydrocarbons because they have fewer hydrogen ATOMS than does an alkane with the same number of carbon atoms, as is indicated in the following GENERAL FORMULAS |
