    For the VSEPR, we learned both the molecular geometry and the electron pair geometry..

    In Kaplan, they give 5 examples.... But in the chem course we learned like 20 or so....

    Would it be safe to just study and know the ones from Kaplan? (Electron pair shape).

    I would just know them all... they really aren't that hard. Better to take a few minutes to learn them than to be kicking yourself if one shows up on the exam.

    yea know all of them. it's not too bad once you understand the pattern and the symmetry of the molecules.

    split it into

    Bonds lone pair electrons
    2 0 = linear
    3 0 = trig planar
    2 1 = bent
    4 0 = tetrahedral
    3 1 = trig. pyramidal
    2 2 = bent
    5 0 = trig. bipyramidal
    4 1 = seesaw
    3 2 = T-shaped
    2 3 = linear
    6 0 = octahedral
    5 1 = sq. pyramidal
    4 2 = sq. planar

    So there's a pattern to the geometry, visualize it 3-D or use a model kit. Once you get it there's no need for memorization since it will be logical.

    Good luck!:thumbup:
