Question

Can double-bonded oxygen partake in hydrogen bonding?

Answer 1

1. Yes, doubly-bonded oxygen $\left(\mathrm{O}\right)$ can still form hydrogen bonding.
2. However, the hydrogen bonds formed by such an oxygen $\left(O\right)$ atom will be weaker than the hydrogen bonds formed by an oxygen $\left(\mathrm{O}\right)$ atom that is singly bonded.
3. Formaldehyde $\left(\mathrm{HCHO}\right)$ and Carbon dioxide $\left({\mathrm{CO}}_2\right)$ both have double-bonded oxygen and high solubilities in water due to hydrogen bonding.
