yes!
This is because in ammonia the direction of resultant dipole is towards lone pair and hence it has high dipole moment but in case of NF3 the direction of resultant dipole moment is opposite to the lone pair and hence the dipole moment gets less.
Because ions are a whole 1+ or 2-, whereas dipoles are "a little bit (-) or a little bir (+)." So the stronger the charge, the stronger the attraction for the opposite charge.And that an Ion has a much bigger electrical charge there fore it attracts with more strenght than a dipole.
they form temporary, weak dipole attractions between molecules
If you are talking about the attraction of water to the ions of the salt, the water is attracted by dipole-dipole interactions.
dipole-dipole force
yes!
HCN and CH3Cl are Dipole-Dipole attractions.
A. One with induced dipole attractions B. One that has hydrogen bonding C. One with dipole-dipole attractions D. One made of polar molecules C. One with dipole-dipole attractions - The molecular solids would have the lowest boiling point because of WEAK INTERMOLECULAR FORCES.

dipole-dipole attractions
Every molecule has a london force (Induce dipole induce dipole force). In this molecule, the intermolecular force that hold these bonds together is dipole-diple interaction or dipolar interaction. There is no hydrogen bonding in here. If there is hydrogen bonding, H-atom must make bond with N,O,F. Therefore, intermolecular forces of NF3 is london force and dipole-diploe
When water is in the form of steam.
Correct answers from Mastering Chemistry: NH3 - hydrogen bonding CH4 - Dispersion forces NF3 - dipole-dipole
A large number of ion dipole attractions can act collectively to disrupt an ionic bond.
Dipole-Dipole attractions
Since the covalent bond between sulfur and oxygen is polar, dipole dipole attractions are present as intermolecular forces.
