  2. Steps to using VSEPR

    1. Draw a Lewis structure for the ion or molecule in question.
    2. Determine the number of electron groups around the central atom. Each lone pair of electrons counts as a single group. ...
    3. Determine the number of lone pairs and the number of bonding pairs around the central atom, and use that to find the molecular geometry.

    What is VSEPR theory?
    In 1957, Ronald Gillespie and Ronald Sydney Nyholm of University College London refined this concept into a more detailed theory, capable of choosing between various alternative geometries. VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules.

    How do you use the VSEPR model?
    Using the VSEPR model, predict the molecular geometry of each molecule or ion. Given: two chemical species Asked for: molecular geometry Draw the Lewis electron structure of the molecule or polyatomic ion. Determine the electron group arrangement around the central atom that minimizes repulsions.

    How does the VSEPR theory apply to simple molecules?
    The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. The five compounds shown in the figure below can be used to demonstrate how the VSEPR theory can be applied to simple molecules.

    What is a VSEPR molecule?
    In the VSEPR model, the molecule or polyatomic ion is given an AX m E n designation, where A is the central atom, X is a bonded atom, E is a nonbonding valence electron group (usually a lone pair of electrons), and m and n are integers. Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP).

    How can VSEPR theory predict molecular geometry?
    « Previous | Next » Valence shell electron pair repulsion or VSEPR theory can be used to predict molecular geometry. The theory is based on Lewis structures and the simple idea that that the preferred geometry around a central atom is the one that minimizes electron repulsion.
