Question

Part 1 involved MeOH addition to form the key tetrahedral intermediate. Part 2 involves loss of H2O from the Map tetrahedral intermediate to form the ester. Part 2 of 2 Intermediate species (from Part 1); Add two curved arrows for the next step. Hö: CH3 er all remaining steps in the mechanism: 1) Draw each species (organic and inorganic) resulting from the previous step. Each step will include all of, and only, the atoms given in the first step i.e., do not use extra reagent molecules/ions, and do not omit spectator ions). 2) Include charges and nonbonding electrons. 3) Add curved arrows for the forward reaction. Note: proton transfers must be drawn out explicitly. Show no more than one H transfer in any one step: all Ht transfers are intormalauta
