Predict the major product for the following reaction. Label whether the reaction will proceed through an SN2, Sn1, E2, or E1 mechanism. SN2 / S1/E2/E1 сн. Br NaCN (1 mol) (1 mol) Predict the major product for the following reaction. Label whether the reaction will proceed through an SN2, SN1, E2, or E1 mechanism. SN27 SN1/E2/E1 NaOCH; Сн,он Draw the line structures of the reactants below and predict the product of their reaction. Label the reaction as SN1, SN2, E1,...
3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored, and then decide whether the reaction pathway goes by a substitution or elimination reaction. SN2 / SN1 E2/E1 Na DMSO,rt...
3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (Syl, SN2, E1, or E2). NaOH HO CH3CH2ON CH3CH2OH CH ON CH OH Br CH,OH Na DMSO
