Determine the electron geometry (eg) and molecular geometry (mg) of XeF4 (Lewis structure is shown) .

eg = octahedral, mg = square planar

eg = tetrahedral, mg = tetrahedral

eg = trigonal bipyramidal, mg = tetrahedral

Consider the molecule below. Determine the molecular geometry at each of the 2 labeled carbons.

C1 = trigonal planar, C2 = tetrahedral

C1 = trigonal planar, C2 = bent

C1 = bent, C2 = trigonal planar

Ammonia, NH 3 , adopts a tetrahedral geometry. However, the non-bonding pair on the central nitrogen atom distorts the bond angle away from the expected 109.5°. Which of the following statements correctly describes how the bond angle is distorted?

The actual bond angle is reduced: it is less than 109.5°

The actual bond angle is increased: it is more than 109.5°

When applying VSEPR theory to predict molecular shape, which of the following do we not need to take into account?

Valence electrons occupying non-bonding orbitals

Valence electrons occupying sigma bonding orbitals

Valence electrons occupying pi bonding orbitals

From the following possible responses, select those responses that give the combination of bonds that makes up a triple covalent bond.

One sigma bond and two pi bonds

Two sigma bonds and one pi bond

A (pi) bond is the result of the

sidewise overlap of two parallel p orbitals.

overlap of two p orbitals along their axes.

sidewise overlap of two s orbitals.
