Draw the organic product for the reaction: CH_3CH_2CH_2OH + K_2Cr_2O_7 (aq) overset{H_2SO_4}{rightarrow}. Essentially, we are drawing the reverse order of Fischer esterification so, in the first step the ester is protonated promoting the nucleophilic attack of water: Notice that just like the Fischer esterification, the process is an equilibrium which makes the reaction a little challenging as it may require higher temperatures and removal of the alcohol as it is formed to push the equilibrium forward. Draw the major product of the hydroboration reaction of this alkene. If water was removed from the reaction mixture, it was cause equilibrium to shift towards methyl benzoate to make water and thus lead to an increased conversion of benzoic acid to methyl benzoate.
