Hydrogen Bonding Calculator

Estimate the maximum number of hydrogen bonds a molecule can form.
Enter donor H atoms (bonded to N/O/F) and acceptor lone pairs to get bonding capacity.

Pick a common molecule (or "custom" to enter values)

Donor H atoms (H bonded to N, O, or F)

Acceptor lone pairs (on N, O, or F atoms)
