Document Summary

Are made up of mainly 2 atoms: All organic compounds contain carbon, c atoms joined together in chains or rings, and almost all contain hydrogen h. The great diversity of organic compounds arises from the unique ability of carbon atoms to combine with themselves (and other atoms) Carbon can form various structures with itself, including linear structures, branch structures, and ring structures. Organic compounds are mostly molecular, (very few are ionic) Many organic compounds also contain o, n, s and a few other atoms appear in what we call functional groups. Involves sharing two or more electron pairs. Holds the nuclei tighter and closer than a single covalent bond. There is 1 electron pair being shared between the atoms. Each atom uses 1 electron in bonding. There are 2 electron pairs being shared between the atoms. Each atom uses 2 electrons in bonding (contributes one electron to each of the 2 pairs) Stronger covalent bond than the single covalent bond.
