What is hydrogen bonding?

Postby alexfwang3g » Sun Nov 10, 2019 11:41 am

A synopsis of the question above in addition to an explanation of why they have to be F, O, or N.

The elements in the second period, F,O, and N have the electronegativity needed to form these bonds.

Hydrogen bonding is a type of electrostatic attraction between a hydrogen atom that is covalently bonded to another atom that is more electronegative than itself, particularly those of the second period:
Fluorine
Oxygen
Nitrogen
Hydrogen bonds are typically weaker than ionic and covalent bonds, but are stronger than Van Der Waals interactions.

Hydrogen bonds form between oxygen, nitrogen, and fluorine atoms and hydrogen atoms. Oxygen, nitrogen, and fluorine are the only ones that are electronegative enough for this type of bond. But, I would also remember that hydrogen bonds are fairly weak.
