In а previоus exаm, we exаmined the fоllоwing reaction: And we found that the nitro group in the para position had a positive value of sigma. A) What does a positive value of sigma tell you about the speed of the reaction with a para-nitro compound? B) Why does this make sense, from the point of view of electronics of the reaction? C) What properties would a reaction have that lead to a negative value for sigma for a nitro group? (Note: I am not asking you to actually propose a reaction, just the properties of that reaction, reasoning by analogy to the earlier parts of this question)
