$$Procedure and Observations

PART A $$ Synthesis

Added $2\mathrm{.}5$ml of methanol $(32\mathrm{.}04$ g$/$mol$),0\mathrm{.}7537$g of camphor $(152\mathrm{.}23$ g$/$mol$),$ and a stir rod to a $25$ mL round bottom flask $($RBF$)$ clamped to a retort stand on top of an ice bath. Stir until dissolved so the solution is clear and transparent. Keeping the ice water bath, add $0\mathrm{.}30$g of NaBH$4(37\mathrm{.}83$ g$/$mol$)$ over $20-30$ minutes while stirring and only adding a small tip while waiting for the bubbles to subside before adding again. Once all the NaBH$4$ is added, remove it from the ice bath and continue to stir until most of the bubbling has stopped and the reaction is at room temperature. Install a consider and place the flask in a $70\backslash$deg C water bath while continuing to stir and maintain the hot plate between seven and six settings. Allow the mixture to reflux for $20$ minutes; vapours should condense and drip back into the flask $($refluxing$).$ Remove from bath and allow to cool to room temperature.

PART B $$ Isolation and Purification

Once the mixture has reached room temperature, add $17\mathrm{.}5$mL of ice$-$cold deionized $($DI$)$ water $(18\mathrm{.}01528$ g$/$mol$)$ to the flask. Filter the opaque white precipitate that forms through a B$$chner funnel and vacuum dry for a minimum of five minutes. Rinse the RBF with cold DI water to remove any remaining precipitate into the B$$chner funnel. Once dry, transfer the white solid to a $50$ mL Erlenmeyer flask using weigh paper, and add $17\mathrm{.}5$ mL of diethyl ether $(74\mathrm{.}12$ g$/$mol$)$ to dissolve the precipitate fully. Crush the precipitate, if needed, to get it to dissolve and$/$or add $2-3$mL more to dissolve the precipitate fully. The solution using anhydrous magnesium sulfate $($MgSO$4)$ and filter, using filter paper, into a clean $50$ mL RBF$.$ Rinse the Erlenmeyer flask with ~$2$ mL of diethyl ether and pour into the funnel to filter out the MgSO$4.$ Rinse one more time, then use a rototap to remove the solvent. Wait for the ether to evaporate, then use gas to dry even more, and proceed to weigh the yield fully.

QUESTION: Show the Full reaction mechanism with ALL arrow pushing, explain the reaction mechanism and connect the procedure steps to the chemistry, explaining the reaction with proper chemical terminology without repeating the procedure.
