QUESTION: dentify and discuss the appearance a disappearance of the assigned major bands in the infrared spectra(labelled A,B,C,D and E) for the two attached compounds. Taking into consideration that appearance and disappearance of the important ones confirms that reaction has taken place HIT-NO- IE93 BCORE- DE BENZOPHENONE 4000 500 SE Fig.1.2 Spectra representation of Benzophenone. BR C-H Stretching aromatics C C o stretch Carbonyl D: C-C Stretch alkene E; C-H bending aromatics

Explanation / Answer

Benzophenone:

B. 3100 to 3000 cm-1 Sp2 C-H stretch

C. 1650 cm-1 carbonyl stretch

D. 1600 cm-1 C=C stretch

E. 690 and 750 cm-1 mono substitution on benzene (C-H bending aromatics)

DiPhenyl methanol:

A. 3500 to 3000 cm-1 OH stretch

B. 3100 to 3000 cm-2 Aromatic Sp2 C-H stretch

D. 1600 cm-1 and 1500 cm-1 *(Aromatic C=C bending)

E. 690 and 750 cm-1 (Aromatic C-H bending sp2).

Conversion of benzophenone to Diphenyl methanol carbonyl stretch at 1650 cm-1 is disappeared and appearence of OH stretch around 3500 to 3000 cm-1.

Remaining all peaks peaks are same in starting material and product.
