- - CARBON’S ABILITY TO FORM BONDS WITH OTHER CARBON ATOMS IS QUITE UNIQUE e.g., DIAMOND, GRAPHITE, FULLERENES - - ALSO FORMS STRONG BONDS WITH OTHER ATOMS: H, O, N, S, HALOGENS e.g., METHANE, CH 4 CHLOROFORM, ? ACETONE, ? ETHANOL, ? CARBON DISULFIDE, ? - - VERY LARGE NUMBER OF COMPOUNDS POSSIBLE - - CAN HAVE A VERY HIGH DEGREE OF COMPLEXITY ( cf. INORGANIC COMPOUNDS) - - HYDROCARBONS: C & H ONLY C - C C = C C C ALK ANES ALK ENES ALK YNES BENZENE (AROMATIC COMPOUNDS) - - e.g. ? - - POLAR COVALENT BONDS: REVIEW ! - - DIPOLE MOMENT: PHYSICAL PROPERTY - - EXPERIMENTALLY MEASURABLE - - UNIT: “ DEBYE “ - - POLAR, NON-POLAR MOLECULES - - POLARITY IS A VECTOR ENTITY - - MAGNITUDE - - DIRECTION - - IF # OF BONDS IN MOLECULE > 1
