Document Summary
Families of organic compounds: an intro to functional groups. Hydrocarbons: contains only carbon and hydrogen atoms, generally very unreactive and are usually used as solvents, subgroups of hydrocarbons, alkane (single bonds), alkenes (double bonds), alkynes (triple bonds), aromatic hydrocarbons (contains benzene) In the structure of ethene, there is resistance to rotation around the c-c axis due to the presence of the extra c-c bond of the double bond: ethene (ethylene) is a major industrial feedstock. It is used in the production of ethanol, ethylene oxide and the polymer polyethylene: propene (propylene) is very important in industry. It is used to make the polymer polypropylene. In these molecules the carbon atoms occur in multiples of 5 the 5 carbons are called isoprene units. Benzene: benzene is the prototypical aromatic compound, benzene does not actually have discrete single and double c-c bonds. This is common mistake so be aware!
