%X Nanoparticles of Fe<sub>3</sub>O<sub>4</sub> and Fe are chemically synthesized by reduction of Fe(acac)<sub>3</sub> using ascorbic acid in controlled condition. It was observed that addition of water during the chemical synthesis process yields Fe3O4 nanoparticles, whereas if the reaction is carried out in absence of water yields Fe nanoparticles¡ªwhich get oxidized upon exposure to air atmosphere. Fe<sub>3</sub>O<sub>4</sub> (15 ¡À 5 nm) and Fe/iron oxide nanoparticles (7 ¡À 1 nm) were successfully synthesized in the comparative study reported herewith. Mechanism for formation/synthesis of Fe<sub>3</sub>O<sub>4</sub> and Fe/iron oxide nanoparticles is proposed herewith in which added water acts as an oxygen supplier. Physico-chemical characterization done by SEM, TEM, EDAX, and XPS supports the proposed mechanism.
