Assign the peaks in the infrared spectrum of triphenylmethanol with frequencies

Question

Assign the peaks in the infrared spectrum of triphenylmethanol with frequencies greater than 1500 cm-1 to specific bond vibrations AND the functional group the bond is associated with. Clearly indicate the specific bond vibration that is associated with the relevant peaks.

23. (3 pts.) Assign the peaks in the infrared spectrum of triphenylmethanol with frequencies greater than 1500 cm to specific bond vibrations AND the functional aroup the bond is associated with. Clearly indicate the specific bond vibration that is associated with the relevant peaks. 3026 1598 3062 890 1330 1157 1450 3464 1010 757

Explanation / Answer

3464 cm-1 is hydroxy stretch, 3062 cm-1 is sp2 C-H stretch and 1596 cm-1 is C=C stretch.

1157 cm-1 is C-O stretch and 690 cm-1 and 750 cm-1 is mono substitution on benzene.
