    Q.

    VSEPR stands for _ theory.

    answer choices

    Varied Structures of Electron Paired and Regrets

    Valence Shell Electron Pair Repulsion

    Valence Structures of Electron Pyramids Revolved

    Q.

    Why is the tetrahedral bond angle 109.5°109.5\degree and not  90°90\degree  ?

    answer choices

    Tetrahedral molecules have four atoms surrounding a central atom.

    Real life molecules are not 2-dimensional.

    Electrons repulsion is minimized at  109.5°109.5\degree  that at  90.0°90.0\degree  .

    All of the above.

    Q.

    Why would one molecule have a specific molecular geometry but a different electron geometry and some have the same geometry for both?

    answer choices

    They are the same.

    Electron geometry represents lone pair electrons while molecular geometry does not.

    This quiz is a piece of pie.

    None of the above
