Hydrogen Bonding with Elements

Postby Jedrick Zablan 3L » Mon Nov 11, 2019 10:30 am

Why are Nitrogen, Oxygen and Fluorine the main atoms in hydrogen bonding? Thanks.

I believe that Nitrogen, Oxygen, and Fluorine are hydrogen bond acceptors due to their high electronegativities. Because Hydrogen would have a partial positive charge, a highly electronegative atom would form a stronger hydrogen bond than an electropositive one.

Nitrogen, oxygen, and fluorine have a relatively high electronegativity. When bonded with a hydrogen atom, these atoms will typically have a stronger partial negative charge, leaving hydrogen with a stronger partial positive charge. This makes the IMF's of these molecules stronger.
