Hydrogen bonding

Postby 905416023 » Mon Nov 11, 2019 6:11 pm

Why can only F, N, and O hydrogen bond? Are there exceptions to this?

Hydrogen bonds are only formed with N,O, and F as they are the most electronegative elements. Bonds formed between hydrogen and other molecules will be too weak to classify as a hydrogen bond.

Adding onto the previous answer, both the electronegativity and small sizes of N, O, and F allow it to bond to H. You can think of H-bonding as a stronger version of dipole-dipole bonds.

I think N,O, and F are the strongest hydrogen bonds so they are specially named as such. Hydrogen can have IMF with other elements but these forces are not as strong.

O, N and F have very high electronegativity as well as a small size. These make it easy for hydrogen bonding to occur since they are not strong enough to break the weak H-bond

Hydrogen bonds occur due to the highly electro negative atoms interacting with hydrogens electrons
