Polar covalent bond
Generally an ionic bond
This is called a hydrogen bond.
The slightly negative end of one polar molecule will be attracted to the slightly positive, hydrogen end of another molecule.
Yes, hydrogen bonds do exist between molecules of hydrogen fluoride. This is because hydrogen fluoride molecules are quite small and are very polar due to the high electronegativity difference of hydrogen and fluorine. As a result, the hydrogen end of each molecule is slightly positive while the fluoride end is slightly negative. The slightly positive hydrogen end of one molecule will be attracted to the slightly negative fluoride end of another molecule, thus forming a hydrogen bond.
They are not attracted to each other because one is polar and one is nonpolar.
In one water molecule, you have the slightly negatively charged oxygen side, and then you have the slightly positive hydrogen end. Because of this, the negative oxygen attracts positive hydrogens and vice versa in separate water molecules. This is where the hydrogen bonds are made.
Water, H2O, is a polar molecule in which the larger, more electronegative oxygen atom develops a partial negative charge, and the smaller, less electronegative hydrogen atoms develop a partial positive charge. The slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule. This weak attraction is called a hydrogen bond. Click on the related link for an illustration of the polar water molecule and hydrogen bonding between water molecules. The dashed lines represent the hydrogen bonds and the δ- represents a partial negative charge, and δ+ represents a partial positive charge.

water - having a slightly negative charge on the oxygen end and a slightly positive charge on the Hydrogen end.
Yes, when combined with Silicon (Si), as in SiH4.
Water molecules are slightly positive on the hydrogen end (the mickey ears) and slightly negative on the oxygen end (the mickey head).
