**Abstract**

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.
