Which of the following correctly defines a hydrogen bond?
A hydrogen bond is: 1. Any bond using hydrogen 2. Found only in non-aqueous systems 3. A specific weak interaction using partial sharing of a hydrogen between more electronegative atoms 4. A covalent bond using hydrogen I don't think it's 3 or 4. Hydrogen bonds are strong. Also they aren't...

Hydrogen bonds are intermolecular bonds where there is orbital overlap and the formation of weak covalent bonds between the hydrogen of one molecule where it is bonded to N, O or F, and the N, O, or F of an adjacent molecule.

Hydrogen bonding in water

H ................H

Of your choices, #3 is the one you should pick.

DrBob1 say: 3 Is the better choice, but your specificity is absolutely required and correct.
-
Dr W say: "3" is the correct answer

H bonds are weaker than covalent bonds. They occur between H in one molecule and a electronegative atom in another molecule.

it's not 1... these are not H bonds... CH4
it's not 2... water H bonds with itself
it's not 4... these are not H bonds CH4
