3. The following Bransted acid-base reactions are all incomplete. First provide the bond-line structures for any missing products or reactants. Use the tables of pKa values available in your textbook to determine whether the equilibrium favors reactants or products. In each case you should show the most favorable possible acidbase reaction between the two reactants. Finally, provide a curved-arrow mechanism for the forward reaction (to show a proper mechanism, you will have to re-draw the reaction with explicit relevant bonds and lone pair electrons). a) =2 products +Li b) c) d) 1 reactant +H3O= 1 product e) 2 reactants +H2S f) 1 reactant 3.
