A) PH3 is ionic, and NH3 is covalent.
B) NH3 forms hydrogen bonds, and PH3 does not.
C) PH3 forms stronger dipole-dipole interactions than NH3.
D) PH3 forms weaker dispersion forces than NH3.
E) PH3 forms dispersion forces, and NH3 does not.
Homework Answers
in NH3 molecule H attached to electronegativity atom N. so NH3 can forms hydrogen but PH3 cannot form.
NH3 is strong intermolecular interaction.
so NH3 has higher boiling points then PH3

Arrange the compounds in order from highest to lowest boiling point.
Arrange the compounds in order from highest to lowest boiling point. Consider how noncovalent interactions would affect the boiling point rather than looking up actual boiling points. Highest boiling point Lowest boiling point Identify the three true statements. Stronger intermolecular forces usually correlate with higher boiling points. Boiling point generally increases with molecular weight due to increased strength of dispersion forces. Hydrocarbons exhibit only dispersion forces. Dipolo-dipole interactions are stronger than dispersion forces and hydrogen bonds. Hydrogen bonds require carbon, hydrogen, and a halogen.

1.Which of the following is expected to have the higher boiling point? fluorine gas chlorine gas bromine gas iodine gas 2.Which of the following statements are true about Intermolecular Forces (IMFs)? (Select all that apply.) Hydrogen bonds occur between hydrogens on two neighboring molecules. All molecules exhibit Dipole-Dipole forces. Hydrogen bonds are generally stronger than London Dispersion Forces. Intermolecular forces are weaker than bonds. Intermolecular forces are attractive forces between two atoms in the same molecule. Only polar molecules exhibit...

C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...

7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...

The boiling point of iodine (12) is much higher than the boiling point of helium (He). Why? O 12 has a larger electron cloud than He, so more energy is required to overcome the stronger London Dispersion Forces. O It requires more energy to break the covalent bonds in 12 than to overcome the London Dispersion Forces between He atoms. The bonds between iodine atoms are stronger than the bonds between helium atoms and therefore harder to break. O 12...
