Help substitution/elimination reactions Give the major product (s) from each of the following reactions being sure to show stereochemistry where important. Is the major product a result of a substitution (S_N1 or S_N2) or elimination (E_1 or E_2) reaction? No reaction is a possible answer.
Predict the major product for the following reactions considering competing substitution and elimination pathways. CI NaOEt NaSH NaOH Explain why a completely nonpolar bond will not give a stretching signal in the IR spectra. Would you expect to see a signal for C-H stretching for a nonpolar molecule? Why or why not?
