Predict the products formed in the following reactions.
Predict the product(s) formed in the following reactions. If there is no reaction, write “No Rxn" as the answer for the major product and leave the minor product box blank. If there is no minor product in the reaction, then leave the minor product box blank. If there are multiple products, make sure the products are in the appropriate box.
