Short Answer

Expert verified

The Structure should be

Step by step solution

01

Apply the given formula

The Given Formula is,C19H9NO2

A set of instauration and fused benzene rings. The IR bond 1724 cm-1 corresponds to the nitrile stretching and the bonds 1600 cm-1 to the carbonyl group.

02

Draw the Structure of the reaction

Therefore, The proton of the group is deshielded and hence the resulting NMR.

The structure has been drawn
