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

Epoxy adhesives are prepared in two steps. SN2 reaction of the disodium salt of bisphenol A with epichlorohydrin forms a “Pre-polymer,” which is then “Cured” by treatment with a triamine such as H2NCH2CH2NHCH2CH2NH2.

Draw structures to show how the addition of the triamine results in a strengthening of the polymer.
