One of the most common reaction pathways involving carbonyl groups that you studied in this course starts with the attack of the group by a nucleophile (Nu-). Draw the mechanism of this first step forming the tetrahedral adduct (intermediate) using arrows to show electron flow. Often, the nucleophilic attack is the rate-determining step of the entire reaction. Briefly explain what factors determine the rate of nucleophilic attack on C=O? PLEASE SHOW ALL YOUR STEPS.
