Explanation / Answer

Conversion of Diphenyl methanol into benzophenone.

IR looks diphenyl methanol ( 3500 to 3000 cm-1 hydroxy stretch, 3100 cm-1 Sp2 C-H stretch, 2900 cm-1 sp3 C-H stretch, 1600 cm-1 C=C stretch, 1050 cm-1 C-O stretch, 690 cm-1 and 750 cm-1 mono substitution on benzene).

Carbonyl stretch at 1680 cm-1 is absent. Therefore your reaction not proceeded. Your reaction TLC is showing two spots (starting material + product) but IR looks Diphenyl methanol.
