Thank you so much! (2 pts) Draw the major elimination products and Identify the mechanism responsible (E1 or E2). If both E and Z isomers form, only draw the E alkene. If only one isomer forms, label the alkene "E,""Z," or neither 1. NaOCH3 а. Br НОСHЗ b. НОСНЗ C. CI NaOCH3 d. (6 pts) Draw the substitution and/or elimination product(s) for the following reactions and identify 2. the mechanism responsible (SN1, SN2, E1, or E2) for each product drawn....
Please, make the answer clear and reable. BrEtOH a OEt Hace H2C Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed ction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss...
