Hydrogen Bonding Sites

Postby Joanne Kang 3I » Sat Nov 23, 2019 11:47 pm

Do hydrogen bonding sites include the lone pairs of the hydrogen bond within the molecule? Ex. H2O

It can have up to 4. The lone pairs on the oxygen can attach to 2 hydrogens and the 2 hydrogens within the molecule can each bind to a lone pair.

yes the 2 lone pairs on oxygen in H2O are both able to form their own respective hydrogen bond with other hydrogens.

Yes, they can each form a hydrogen bond. This is because they are both negatively charged, and will push away from each other but towards a partially positive hydrogen.
