How many hydrogen bonds between a u
WebTo understand hydrogen bonding in Ammonia (NH3) we need to know that Ammonia is a polar molecule. This means that it has a positive and a negative "side".Be... WebA hydrogen bond is an attraction between a hydrogen atom and an electronegative atom, with only nitrogen (N), oxygen (O) or fluorine (F) [1]. Hydrogen bonds appear frequently within biological molecules and exist in polar compounds. A common example of this is water, where the attractive interaction exists between the oxygen and hydrogen atoms.
