Question

Complete the electron-pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for each step. Make sure to include all nonbonding electron pairs.

Complete the mechanism for the conversion of the following deuterated alcohol to deuterated chloroalkane via the mesylate intermediate by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows. Also, select the correct absolute stereochemistry of the starting material and the final product. (Note the use of a generic alcohol representing the deuterated alcohol as a proton shuttle.)
