Is a hydrogen a very strong dipole-dipole force?
The hydrogen bond is not strong.
WHYNh3 is stong bond?
NH3 is a strong bond because it is capable of hydrogen bonding. when it comes to intermolecular forces (dispersion, dipole-dipole, hydrogen bonding, and ion-dipole) hydrogen bonding is one of the strongest. Molecules containing Hydrogen atoms bonded with Flourine(ex-FH), Oxygen(ex-H2O), or Nitrogen(ex-NH3) are capable of hydrogen bonding because they are extremely polar. Even though the Nitrogen and Hydrogen atoms "share" atoms through covalent bonds, the electrons tend to hover closer to Nitrogen. This results in the Hydrogen atoms becoming partially positive in charge while the Nitrogen atom gains a partially negative charge. When a molecule of NH3 comes in contact with another molecule of NH3, the positive (Hydrogen) end of one molecule attracts the negative (Nitrogen) end of the other. This ability of the partially positive Hydrogen atoms to form strong bonds with other polar molecules (IE. Hydrogen Bonding) is why NH3 forms strong bonds.
What attractive force must be overcome to melt ice?
The strong Hydrogen Bond needs to be overcome to melt ice. A hydrogen bond is basically a dipole-dipole bond that's really strong (slight negative attracted to slight positive). Remember Hydrogen bonds are H-O, H-N, H-F, so specifically, H-Bonding forces need to be overcome.
Forces of attraction between molecules of the same kind are called what?
"Intermolecular forces". Which can be of four types:1. Dispersion Forces - http://www.answers.com/topic/van-der-waals-force2. Induced Dipole Interactions, which occur when the polarity of one molecule polarizes another3. Dipole-Dipole Interactions - http://www.answers.com/topic/dipole-dipole-interaction4. Hydrogen Bonding - http://www.answers.com/topic/hydrogen-bonding
What forces hold the molecules of a liquid together?
strong
A hydrogen bond is approximately how many times higher in energy than a dipole-dipole interaction?
hydrogen bonding is about five times as strong as dipole interaction

Hydrogen bonding is a strong convalent bond?
No. Hydrogen bonding is a strong intermolecular force. It is not a true bond.
Which of the following is a very strong dipole-dipole force?
A Hydrogen Bond. -Apex
What is a strong dipole-diploe attraction between molecules that contain a hydrogen atom bonded to a small highly electronegative atom with at least one lone electron pair called?
hydrogen bonding
What type of bond is hydrogen?
A hydrogen bond is a very strong dipole-dipole bond. A hydrogen bond can only form between hydrogen and a strong electromagnetic atom; fluorine, oxygen or chlorine.
Rank the intermolecular forces in order from strongest to weakest?
The strongest intermolecular force is Hydrogen Bonding! Hydrogen atoms have a very strong attraction to Fluorine, Oxygen, and Nitrogen atoms, a molecule with Hydrogen and a molecule with F, O, or N will form strong hydrogen bonds. Just remember FON or NOF. (It's important to note that hydrogen bonding does NOT occur with hydrogen atoms that are bonded to carbon atoms.) The second strongest is dipole-dipole attraction. Some molecules are polar, meaning they have a positive and negative pole, kind of like magnets. And just like magnets, two polar molecules attract because one's negative pole is attracted to the other's positive pole. The weakest of them all is London Dispersion force. This force exists between all molecules, no matter what atoms are in them. Basically, as electrons fly around the nuclei of atoms, they'll often create a very weak dipole that exists only for a tiny fraction of a second. Basically these LD forces are just like D-D forces except weaker.
Which intermolecular force would cause the highest boiling point?
van der waals force
