Draw the orthonitrophenolate product which absorbs light at 420nm.

What is the relationship between benzophenone and benzhydrol. Looking at their NMR, what changes would happen to benzophenone to benzhydrol?

The following molecule undergoes an intramolecular reaction in the presence of pyrrolidinium acetate, the protonated form of pyrrolidine. Draw the product of this reaction, assuming that a dehydration reaction takes place.

Compound A has molecular formula C8H8O. Its 1H-NMR spectrum shows a singlet of integral 3 at 2.58 ppm and a multiplet of integral 5 at 7.84 ppm. Its 13C-NMR shows six signals. The IR spectrum of A shows a noteworthy stretch at 1698 cm-1. - Identify Compound A, explaining your reasoning Compound A is treated with a mixture of nitric and sulfuric acids to generate Compound B. The 1H-NMR spectrum of B shows three singlets, one at 2.52 pm of integral 3, one at 6.67 ppm of integral 1, and one at 7.94 ppm of integral 2. The 13C-NMR spectrum of B shows six signals. - Identify compound B, explaining your reasoning Compound B is treated with methylmagnesium bromide and then aqueous acid to generate compound C. The 1H-NMR spectrum of C shows four singlets, one at 1.42 ppm of integral 6, one at 2.3 ppm of integral 1, one at 8.52 ppm of integral 2, and one at 8.97 ppm of integral 1. The 13C-NMR spectrum of C shows six signals. The IR spectrum of C shows a noteworthy broad stretch at 3326 cm-1. -…
