The intermolecular force of toluene is primarily London dispersion forces, which are weak attractions between temporary dipoles in molecules. Toluene, being a nonpolar molecule, experiences these forces due to the momentary fluctuations in electron distribution.
The strongest intermolecular force between hydrogen chloride molecules is dipole-dipole interactions. Hydrogen chloride is a polar molecule with a permanent dipole moment, so the positive hydrogen end of one molecule is attracted to the negative chlorine end of another molecule, leading to dipole-dipole interactions.
The strongest intermolecular force in CCl2H2 (dichloromethane) is dipole-dipole interactions. This is because dichloromethane has polar bonds due to the difference in electronegativity between carbon and chlorine, resulting in a permanent dipole moment.
The strongest intermolecular force in NaBr is ionic bonding, which occurs between Na+ cations and Br− anions. Ionic bonds are strong electrostatic attractions between oppositely charged ions.
hydrogen bonding
Not particlarly it is weaker than the electrostaic attraction between ions but is the strongest of the intermolecular forces.
The strongest intermolecular force in ammonia is hydrogen bonding. This occurs because the nitrogen atom in ammonia can form a hydrogen bond with a hydrogen atom from another ammonia molecule, resulting in a relatively strong attraction between the molecules.
The strongest intermolecular force in PF3 is dipole-dipole interaction, which occurs between the partial positive and negative charges on the molecule. This is because PF3 is a polar molecule due to the differences in electronegativity between phosphorus and the fluorine atoms.
Hydrogen bonding is typically the strongest intermolecular force due to the strong dipole-dipole attraction that occurs between molecules with a hydrogen atom bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine.
The strongest intermolecular forces that would exist between molecules of NO would be dipole-dipole attractions. There are no hydrogen bonds formed, and so dipole-dipole would be the strongest. There will also be dispersion forces, but these are weaker than dipoles.
The intermolecular force of CH2O (formaldehyde) is dipole-dipole interactions. This is because formaldehyde has a polar covalent bond between carbon and oxygen, leading to partial charges on the atoms, resulting in dipole moments.
The strongest intermolecular force present in ibuprofen is dipole-dipole interactions. Ibuprofen contains polar covalent bonds due to the differences in electronegativity between the atoms, leading to the formation of partial positive and negative charges. These partial charges allow ibuprofen molecules to attract each other through dipole-dipole interactions.
