| Organic Acid | Organic Base |
| Organic compounds behaving like acids | Organic compounds behaving like bases |
| Relative stability of the conjugate base determines the strength of acid | Inductive effect determines the bases’ strength |
| Releases proton in aqueous solution | Organic bases do not always accept protons |
| Examples: carboxyl group, sulphonic group, hydroxyl group, phenol group, thiol group. | Examples: amines and nitrogen containing heterocyclic compounds. |
