The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive To understand hydrogen bonding, just remember that this type of bonding ONLY occurs in the following cases: In the case of ammonia, NH3, nitrogen is bonded to hydrogen. You should also know that this force is caused due to the temporary attraction between the electron-poor region of one molecule, and the electron-rich region of the other. A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. The negative charge of its lone pair of electrons is spread out over a greater area and is not strong enough to attract the partially positive hydrogen atom. There are three major types of intermolecular forces: London dispersion force, dipole-dipole interaction, and ion-dipole interaction. 7 Why hydrogen fluoride is hydrogen bonding? What type(s) of intermolecular forces are expected between CSe_2 molecules? Although it contains polar bonds, it is a symmetrical molecule and so the dipole moments cancel each other out.
