This long lifetime means a greater chance that the CFC will start an ozone destruction chain reaction instead of being consumed by some other chemical reaction. A good greenhouse gas must be efficiently absorb infrared radiation. These absorb infrared. These do not absorb infrared. Atoms in a molecule are arranged to minimize and evenly distribute electron repulsion.
Water is a bent molecule.
