For the cycloaddition reaction shown below A B NC CN a) Give the curved arrow-pushing and draw the allowed product for the reaction, be sure to include stereochemistry and indicate any racemic mixtures b) on TOP of reactant A draw a pictorial representation of the HOMO (draw it on the structure like the one shown below rather than the one in the equation so that the curved arrow-pushing isn' obscured) A heat c) on TOP of reactant B draw a pictorial representation of the LUMO (draw it on the structure below rather than the one in the equation so that the curved arrow-pushing isn't obscured) B NC CN

2. a. b. d. C. oFor each reaction, draw the product(s) and circle the mechanism(s). Include "major be and “minor" when necessary. Stereochemistry must be included for stereoselective reaction "No reaction" is a possible answer.
