The proposed solution to this roadmap problem has several errors. I am assuming that $\ce{K2Cr2O7}$, methanol and $\ce{LiAlH4}$ are employed in excess. In the oxidation of 1 (A), chromic acid, $\ce{H2Cr2O7}$, is formed from $\ce{K2Cr2O7}$. To obtain the purported hydroxy acid 6 suggested in the solution, exclusive oxidation of the primary alcohol would be ...
Welcome on Chemistry SE! Here, you are doing an esterification, done with your carboxylic acid and methanol with $\ce{H+}$. The problem is, the yield for such reaction is quite low (an average 67% for a primary alcohol, because of the equilibrium between esterification and hydrolysis). A solution to increase it is to use an excess of reagant (preferably the ...
