Explanation / Answer

Solution :-

For the given IR spectrum

It shows the major peaks at the 3000 cm-1 and 2850 cm-1 which are the peaks for the C-H bond

The peak at the value of the 1649 is the aromatic C=C bond peaks

Peak around the 650 to 680 cm-1 are the C-H aromic bond peaks

The peaks from the 1300 to 1500 cm-1 are for the amide groups R-CO-NHR

The peaks in the range of the 700 to 1000 cm-1 range are the figure print region peaks.
