N2O
N3−

    Is the idea here for you to know the Lewis electron dot structure?
    Draw the Lewis structure, then determine the shape of the molecule.
    In order for a molecule to be polar the following two criteria must be satisfied.
    1. There must be a difference in electronegativity between the central atom and one of the other atoms, AND
    2. The molecule must not be symmetrical in three dimensions.

    SO2 polar
    N2O polar
    N3- non polar
    ?

  • Chemistry -

    SO2 polar
    N2O polar
    N3- non polar
    ?

  • Chemistry -

    Those look ok to me. N2O is linear but polar.

  • Chemistry -

    it tells me that it is incorrect..

  • Chemistry -

    N3- is an ion.

  • Chemistry -

    so
    N20 is polar
    SO2 is polar
    and N3- is ionic
    ?

    I should have read the instructions as bob Pursley did.
    Would the following structures be polar or nonpolar? (Not applicable if the structure is an ion. Pick "ionic" in that case).
