Consider the following compounds shown below and think about the kinds of intermolecular forces present in a pure sample of each compound. Which of the following statement(s) is/are correct? CH2F2                 CH3NH2                  CH3CH2CH3                HCOOH               NaF Only two compounds are capable of forming hydrogen bonding interactions Only one compound will exclusively have London dispersion forces as the only intermolecular force present (no other intermolecular forces present) Four compounds can form dipole dipole interactions

Determine which of the following molecules are polar and choose the correct reasoning for your answer. W and X W and Y X and Z Because All the bonds in the molecules are polar, however they cancel out due to the molecular geometry, resulting in no net dipole. All the bonds in the molecules are polar, however they do not cancel out due to the molecular geometry, resulting in a net dipole All the bonds in the molecules are non-polar, hence they do not cancel out due to the molecular geometry, resulting in a net dipole.

Consider the following information about elements A and X below Element Period Number of valence electrons A 3 or greater 8 X 2 7   Predict the molecular geometry of the molecule AX4?
