What is the relationship between polar molecules and hydrogen bonds?
I was wondering (actually it's homework) what the relationship between polar molecules and hydrogen bonds is. Which you should know if you read the question but...

hydrogen bonds are polar bonds...think of water. h2o, in a beaker of water the h's and o's bond to eachother via hydrogen bonds. oxygen is more electronegative than h is so it has a partial negative charge on it, meanwhile the h is left with a partial positive charge.
of course the partial positive and negative charges are attracted to eachother, and so they form a bond. it is a polar bond because of the attraction of the partial +ve and -ve charges, and polar interations are involved (remmeber, O is more electronegative than H)
hydrogen bonds are still weak compared to covalent bonds though

Water molecules have two polar bonds. Oxygen is a more electronegative atom than hydrogen, thus the distribution of electrons between the H-O-H bonds is asymmetric causing the hydrogen to have a partial positive charge and the oxygen to have a partial negative charge.
In hydrogen bonding the oxygen and hydrogen atoms on adjacent water molecules associate electrostatically to neutralize the dipoles.
For the answer above mine, it is partially correct. They do not form a polar bond. The H and 0 atoms on separate water molecules interact electrostatically.

water is between the main polar solvent> this means that water is a dipole with oxygen atom adverse and hydrogen valuable. With that residences water disooles esily the two molecule having comparable charateristics , acids, bases, salts and extra many times all molecules having a dipole 2nd
