Hydrogen Bonding

[Kennedi2J]

If hydrogen bonding is present does that always mean the molecule is polar?

[Philip]

It happens with polar molecules with N, O, F, elements that have lone pairs that attract Hydrogen

[Kevin Liu 1J]

Since hydrogen bonding requries partial positive/negative bonding between Hydrogen (partial positive) and N, O, F (partial negative, it is usually polar.

[gferg21]

Hydrogen is always positive in an atom, so the electrons are going to be pulled away from it in a compound to make them more positive. This means that there will be polarity because the atom it is bonding to will be the one receiving the electron from hydrogen.

Typically, yes, because the hydrogen is attracted to atoms N, O, and F, that have stronger partial negative charges.

[kpang_4H]

Typically, yes, because the hydrogen is attracted to atoms N, O, and F, that have stronger partial negative charges.

I would also add that the N O F atoms must have a lone pair for hydrogen to bond.

[Simon Dionson 4I]

Yes, but the atom would have to have a partially positive on the hydrogen and there would have to be a strongly electronegative atom, like N, O, or F

[SMIYAZAKI_1B]

Commonly, hydrogen bonding is polar due to its nature of bonding only with N,O, and F. Since hydrogen isn’t high on electronegativity, the difference will always be larger towards the other element.

[Jacob Villar 2C]

Yes, since hydrogen bonds form with the elements N, O, and F, and these are more electronegative atoms.

[kendal mccarthy]

Yes, because in the ranking of powers of IMF's hydrogen bonding is a specialized kind of dipole-dipole bonding which is actually stronger, so if a molesule has H bonding it will be polar.

[Matthew Tsai 2H]

Yes, generally with the conditions necessary for hydrogen bonding to occur, which is hydrogen bonded to a very electronegative atom (F, O, or N), the resulting molecule would be polar.

[Alfred Barrion 2H]

Yes, hydrogen bonding should have a partial positive or negative charge.

[Caitlin Ciardelli 3E]

Yes. This is because Hydrogen's partial positive charge is attracted to a partial negatively charged atom (Nitrogen, oxygen, or fluorine) to create a hydrogen bond. This is why the resulting molecule is polar! Hope this helps :)

[Laura WM 3I]

Isn't it possible for hydrogen bonding to occur in a symmetrical formation that would cause dipole moments to cancel and the whole molecule to be non polar?
