CH3F
CH4
Which of the following show the changing of INTRA molecular forces? Check ALL that apply. It may be one or more than one.
CH4(g) --> CH4(l)
NH3(g) --> 1/2N2(g) + 3/2H2(g)

H2Te has a boiling point of -2 C while H2Se has a boiling point of -41 C. Which of the following BEST explains this?
H2Se can form H-bonds while H2Te cannot
H2Se must break weaker intermolecular forces to boil while H2Te must break stronger intramolecular forces to boil
H2Te is more polar than H2Se and therefore has stronger dipole-dipole forces
H2Te has more electrons and therefore has stronger london dispersion forces
Silicon has a melting point of 1414 C while I2 has a melting point of 114 C. Which of the following BEST explains this data?
I2 is a molecular solid held together by weaker intermolecular forces than Si which is held together by intramolecular forces
Both I2 and Si are molecular solids but Si has fewer electrons resulting in stronger intermolecular forces
Si is a network material and held together by strong intermolecular forces while the bond between the I atoms is weak due to the large size of the I atom
None of these
Which of the following would be expected to have the highest boiling point?
Which of the following would be most likely to dissociate (dissolve) in water?
NH4Cl
Ba(OH)2
Ca3(PO4)2
BaSO4
