- The following halide reacts differently with hydrogen sulfide as shownshown in the attached image reactions. For each reaction, show the mechanism, draw the energy diagrams for the formation of each product and write the rate equation for the formation of each product. PD: mechanisms are SN1,SN2,E1 etcc. Snl reactions dominate under polar protic solvents. Increasing the polarity of the solvent will increase the rate of the reaction because the polar solvent will stabilize the dispersed charges on the transition state more than it will stabilize the neutral reactant.
