Which one of the following statements about Reaction M is correct? N is the major product N is the minor product N and O are formed in equal amounts Not including organic by-products how many organic products are formed in Reaction P? How many organic products arise from the treatment of compound Q with H_2 in the presence of Pt metal? I think you get one since it forms a syn-addition.
