This question has multiple parts. Work all the parts to get the most points. Propose a mechanism to account for the formation of a cyclic acetal from 4-hydroxypentanal and one equivalent of methanol. If the carbonyl oxygen of 4-hydroxypentanal is enriched with oxygen-18, do you predict that the oxygen label appears in the cyclic acetal or in the water? $OH \quad + \quad CH_3OH \quad \longrightarrow \quad \text{A cyclic acetal} \quad + \quad H_2O$ 4-Hydroxypentanal (racemic) (a) Step 1 of 5: Draw the structure of the hemiacetal initially formed. Only show specific types of hydrogen atoms: $\bullet$ Hydrogen atoms not attached to carbon atoms. $\bullet$ Apply formal charges where appropriate. $\bullet$ Assign lone pairs and radical electrons where appropriate. $\bullet$ Do not show stereochemistry if applicable.
