VSEPR - Bonding and Molecular Geometry

  1. Oct 23, 2013 #1
    1. The problem statement, all variables and given/known data
    What is the electron pair geometry of the following?
    SCN−
    BeCl2
    O3

    3. The attempt at a solution
    SCN− Linear
    BeCl2 Linear
    O3 Trigonal Planar


    1. The problem statement, all variables and given/known data
    Would the following structures be polar or nonpolar? (Not applicable if the structure is an ion. Pick "ionic" in that case).
    NO2+
    XeF2
    ClO2−

    3. The attempt at a solution
    NO2+ ionic
    XeF2 nonpolar
    ClO2− ionic


    1. The problem statement, all variables and given/known data
    What is the bond angle at the central atom of the following?
    ClF2+
    HCN
    SO2

    3. The attempt at a solution
    ClF2+ 109
    HCN 180
    SO2 120

    Can you explain? Isn't there a lone pair in the center Oxygen atom?

    Of course you are right, sorry. Was thinking in another question.

    It is linear and symmetric, so can't have a dipole moment.
