How do hydrogen bonds hold molecules together
WebHydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF). In these molecules, the hydrogen atoms do not pull as strongly on the shared electrons as the N, O, or F atoms. WebBoth hydrogen atoms have only one electron, but by forming a single covalent bond, both can have a full outer shell. The shape of the molecule formed is called linear. A shared pair of...

WebThe forces holding two molecules together in a hydrogen bond are much stronger than those between molecules and hydrocarbons. The attraction between hydrogen and oxygen atoms results in a much higher boiling point of water than anticipated for a different molecule with the same mass. WebFor example, sodium chloride (NaCl) is an ionic compound that consists of a multitude of strong ionic bonds. Sodium chloride melts at 801°C. On the other hand, ice (solid H 2 O) is a molecular compound whose molecules are held together by hydrogen bonds, which is effectively a strong example of an interaction between two permanent dipoles ...
