Question
Chapter 9, Problem 24P
Interpretation Introduction
Interpretation:
The structures for O and P are to be proposed on the basis of the given information.
Concept introduction:
In NMR, the chemical shift of the nucleus depends on the relative electron density around an atom. Attached with highly electronegative atoms means highly deshielded and higher will be the chemical shift value.

Compound A is treated with HONO,
followed by a reaction with Compound B; the
final product obtained is shown below. H NMR
spectra for Compounds A and B are provided.
(a) Provide structures of Compounds A and B in
the boxes below.
(b) Label the signals on each spectrum with letters
(as outlined on Week 3 Tuesday slide 4), then
assign all H NMR signals to specific chemical
environments or specific protons on the
structures of Compounds A and B.
