Question: what is the difference between a saturated and an unsaturated hydrocarbon?
Answer: A saturated hydrocarbon is the hydrocarbon in which all its carbon-carbon bonds are single. e.g alkanes like ethane ,propane. An unsaturated hydrocarbon,however, is the one in which some carbon-carbon bonds can be double or triple. e.g alkenes like ethene have double bonds while alkynes like ethyne have triple bonds.
