14. Predict the integration and multiplicity of each signal that would be observed in the 'H NMR of the following compound. Do so by first identifying and labeling equivalent protons (A, B, C, etc.). Then complete the chart. Which signal will appear most downfield? Proton Label Integration Splitting Pattern is most downfield.

Provide the 1H and 13C NMR data for thiophenol. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported. Provide the 1H and 13C NMR data for the product generated in Question #1. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported.

assign each signal from this spectrum in terms of integration and
multiplicity and predict the structure of the product . the
reaction acheived was the hetero Diels- Alder cycloaddition!
thanks
okay , actually N- phenylurazole was mixed with oxone(potassium
peroxomonosulfate) and dichloromethane and potasium bromide!
more data required like what? be more specific please! in this
reaction the mixture of N- phenylurazote , potassium
peroxomonosulfate, potassium bromide and cycloheptatiene was used
as reactants!
