1. The problem statement, all variables and given/known data To convert acetaminophen to phenacetin it was added NaOH in ethanol and then Ethyl iodide. (Nucleophilic substitution). What would be the change in reaction velocity if insted of Ethyl iodide it was added 2-iodopropane (Isopropyl iodide) 2. Relevant equations 3. The attempt at a solution what affects the velocity of the reaction? Is it the stability of the reaction of NaOH with Acetaminophen? If it is, then the velocity is the same although I'm not sure..
