    what is the general theory??

    well you find the partial charges and if one side is more charged (i.e H2O) then its a polar molecule

    If you compare the CO2 molecule to the H2O molecule you will see that CO2 is symmetrical whereas H20 is asymmetrical. This is what leads to the imbalance in charge.

    Well, Wiki was my choice, not the OP's, and I am merely refering to it to show the diagram of the molecules. Even Wiki couldn't screw that up...

    lol
    well i cant explain it better than to say that the angle of the bonding affects the polarity
