Predict the products of the reactions below, and show the mechanism for each reaction by using curved arrows to indicate the movement of electrons. If there is no reaction, please write "NR". Note that these problems involve substitution and acid/base reactions. (a) The pka value of the thiol group (RSH) in this molecule is about 11. THF stands for tetrahydrofuran and is just the solvent (not involved in the reaction). SH Li Br in THF
