The Strength of Hydrogen Bonding

Postby Jedrick Zablan 3L » Mon Nov 11, 2019 10:39 am

Are hydrogen bonds the strongest intermolecular force? If so why? Thanks.

Although hydrogen bonds are one of the strongest intermolecular forces, ionic and covalent bonds are still stronger.

Hydrogen bonding is one of the strongest intermolecular forces because it involves a permanent dipole and there exists a high electronegativity difference between the H atom and an N,O, or F atom, leading to a greater attraction.

since F, O, and N are the three most electronegative elements, and H is very positive, hydrogen bonds are very strong and hard to break apart

although they are strong, hydrogen bonds are not stronger intermolecular forces than covalent or ionic bonds so they are not the strongest overall. It is a permanent dipole of sorts and is stronger than typical dipole-dipole attractions.
