Answer the questions below based on the spectra Write a mechanism for the formation of semicarbazones. Suggest a reason why the NH2 group depicted in the reaction scheme is the one used to form the semicarbazone and not the other NH2 group. Yes, the answer is resonance, but you really want to explain how resonance affects the reactivity of the non-reacting NH2 group. Explain why the 2,4-dintrophenylhydrazone is colored and the semicarbazide is not. The reason should relate to the structure.
