Interactions

Polarity
Often weakly polar or nonpolar unless other structural features dominate.
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.
