PROBLEM 5. Reaction Mechanism 1. Propose products (major/minor) and provide a detaile reaction mechanism to account for the formation of the major product. Use curved arrow notation to indicate electron flow. Also, draw a structure of the transition state that accounts for the formation of the major product HЕr он 0° C major minor transition state corresponding to the major product of 20 points
