I need help with this worksheet!

1. Add 'diene" and "dienophile" labels to the starting materials and predict the products of the following [4+2] cycloaddition reactions. Ignore stereochemistry, but follow the "major" and "minor" labels in the boxes to indicate which regioisomer is favored (hint: consider resonance effects of the substituents) Ph [4+2] O diene 18 diene dienophile: dienophile major minor [4+2] diene dienophile; 8 diene O dienophile major minor 2. Draw the diene and dienophile that could lead to each of the following cycloaddition products. Draw the competing regioisomers. Add "major" and "minor" labels to the products to indicate which regioisomer is favored (hint: consider resonance effects of the substituents). Ignore stereochemistry. [4+2] Ph diene dienophile major major minor ! .minor [4+2] diene dienophile major major minor minor
