This is free radical reaction and reduction of benzophenone occurred by UV irradiation. Free radical on benzophenone due to photo excitation abstract hydrogen from isopropanol and gives benzopinacol and acetone. Chemically benzophenone is 1‚1‚2‚2‚ tetraphenyl 1‚ 2 ethylenediol. Benzopinacol can easily isolate from reaction mixture by suction pump and characterized by using common analytical techniques like UV‚ IR etc. Keywords: Photochemistry‚ benzophenone‚ benzopinacol‚ free radical.
