Question

1) How do lone pairs of electrons influence the structure of molecules?
2) What does VSEPR stand for? In VSEPR theory, what determines the shape of the molecule?
3) Draw an appropriate Lewis structure for the following molecules and attempt to predict their shape: H2S, CH4, XeF4
4) Give a molecular example for each type of intermolecular force: (a) dipole-dipole (b) ion-dipole (c) dispersion forces (d) van der Waals forces 5) Determine if the molecules from question 3 are polar or nonpolar. Explain your answer.
