Interactions
- Polarity
- Often polar; exact polarity depends on size, substitution, and ionization state.
- Acid-base behavior
- Review ionizable groups and pKa data where available; ChemForge does not infer definitive acid-base state from identity alone.
- Intermolecular forces
- Assess dispersion, dipole interactions, hydrogen bonding, and ionic character from the functional groups shown.
