Which molecules have hydrogen bonding among themselves?

Question

Which molecules have hydrogen bonding among themselves?

Answer 1

Molecules that have Nitrogen, Oxygen and/or Flourine together with Hydrogen

Answer 2

Do you mean 'within' themselves?

If so, then proteins do. Hydrogen bonds are one means by which their 3D structure is maintained.

Answer 3

Those would be the ones where hydrogen is covalently bonded to either F, O, or N, so that the hydrogen of one molecule is attracted to the F, O, or N of an adjacent molecule.

The hydrogen bond is the intermolecular attraction, the one between two different molecules.

Answer 4

Hydrogen bonding is made usually between hydrogen and other very strongly electronegative atoms like oxygen,fluorine, nitrogen.Hydrogen bond can be made by any other weak electronegative atom but the second partner would always be a strong electronegative atom as I've told.The simplest example of hydrogen bonding can be seen in between water molecules where the hydrogen of one molecule makes the hydrogen bond with oxygen of nearby molecule and this process continues
