Organic compounds are typically... - (answer)insoluble in H2O and form
covalent bonds
What do hydrocarbons contain? - (answer)only carbon and hydrogen
What is an aliphatic hydrocarbon? - (answer)A hydrocarbon containing carbon
and hydrogen joined together in straight chains, branched chains or non-
aromatic rings.
What is an aromatic hydrocarbon? - (answer)A hydrocarbon with a benzene
ring and alternating double bonds.
What is a saturated hydrocarbon? - (answer)A hydrocarbon containing only
single-bonded carbon atoms.
What is an unsaturated hydrocarbon? - (answer)A hydrocarbon containing at
