Question #44496

An alkene $X$ ($\ce{C6H12}$) on reductive ozonolysis yields methanal and 2,2-dimethylpropanal. $X$ is subjected to three distinct hydration protocols at 298 K:

I. Catalytic hydration with dilute $\ce{H2SO4}$ yields $P$ as the major product. II. Hydroboration-oxidation ($\ce{B2H6}$ in THF, followed by $\ce{H2O2}$/$\ce{NaOH}$) yields $Q$ as the major product. III. Oxymercuration-demercuration ($\ce{Hg(OAc)2}$/$\ce{H2O}$, followed by $\ce{NaBH4}$/$\ce{NaOH}$) yields $R$ as the major product.

Identify the IUPAC names of $P$, $Q$, and $R$ respectively.
