Document Summary
Biol 205 the compound of cells chapter 3. Carbon is the building block of organic compounds because it alone is capable of forming single, double, or triple bonds with itself and other atoms (can branch or bond with up to four other atoms) Hydrocarbons: compounds composed of only carbon and hydrogen that bond together in various combinations: simplest hydrocarbon is methane (ch4, carbon can form covalent bonds with other carbons (ie. graphite) Rings cyclic or aromatics: pure hydrocarbons are insoluble in water because they have nonpolar covalent bonds (this makes them hydrophobic) Because hydrogens bonded to carbon do not have dipoles (a pair of equal and oppositely charged poles separated by a distance), they cannot form bonds with water. Water forms a clathrate cage (the guest molecule is in a cage formed by the host molecule) ie. shaken salad dressing has droplets of oil in water.
