Can hydrogen bonds only form when the hydrogen atom is involved in a polar bond?

Yes. When it bonds with F O or N. the electro negativity of these atoms pull the electrons so close, H becomes somewhat of a naked proton which can then hydrogen "bond" with other F O & N atoms close by.

What chemical bonds would you find in pure water?
In each water molecule each hydrogen atom forms a polar covalent bond with the hydrogen atom.
In a single molecule of water the two hydrogen atoms are bonded to a single oxygen atom by?
covalent bonding
What can water molecules form hydrogen bonds with?
Water is composed of Two Hydrogen atoms that form a polar covalent bond with an oxygen atom.
What bonds does water form between hydrogen and oxygen?
Covalent bonds hold the atoms together in a water molecule. In covalent bonds atoms share electrons.
What accounts for its extraordinary strength of the hydrogen bond?
Bonds that make-up hydrogen bonds are polar, and therefore, very strong. This gives the hydrogen atom a positive charge that is almost half as large as that of a proton. The small size of the hydrogen atom allows the atom to come very close to unshared pair of electrons on an adjacent molecule.
What types of bonds hold together a water molecule?
Water has covalent bonds.The bonds between atoms in a water molecule are covalent bond, somewhat polar ones.
Define hydrogen bond?
forms when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom

What accounts for hydrogen bonds for its extraordinary strength?
Bonds that make-up hydrogen bonds are polar, and therefore, very strong. This gives the hydrogen atom a positive charge that is almost half as large as that of a proton. The small size of the hydrogen atom allows the atom to come very close to unshared pair of electrons on an adjacent molecule.

Is covalent bond between an oxygen atom and a hydrogen atom O-H polar?
yes. Bonds between a non-metal and a non-metal are covalent. Bonds between a non-metal and a metal are ionic.
A water molecule is held together by what kind of bond?
The water molecule itself is held together by polar covalent bonds between the oxygen atom and the two hydrogen atoms.
Do hydrogen bonds REsult from the loss of neutrons by an atom?
Hydrogen bond doesn't involve neutrons. A hydrogen bond is the electromagnetic attractive interaction of a polar hydrogen atom in a molecule or chemical group and an electronegative atom, such as nitrogen, oxygen or fluorine, from another molecule or chemical group.
Why is it necessary for there to be a polar covalent bond in order for a hydrogen bond to occur?
A hydrogen bond occurs when a hydrogen atom from one molecule is attracted to an atom (usually oxygen) of another molecule. There is a small positive charge on a hydrogen atoms in many covalent bonds due to H's very low electronegativity. This results from a polar covalent bond. Likewise, there is usually a small negative charge on an oxygen atom in a covalent bond due to O's relatively large electronegativity. This is also the result of a polar covalent bond. The +/- attraction that results from these polar bonds is what a hydrogen bond actually is. In the absence of a polar covalent bond, there will be no residual charge left on either the hydrogen or the oxygen and therefore no hydrogen bonding will occur!
