Compound A, C₈H₁₆, undergoes catalytic hydrogenation to give octane. When treated with meta- chloroperoxybenzoic acid, A gives an epoxide B, which, when treated with aqueous acid, gives a compound C, C₈H₁₈O₂, which can be resolved into enantiomers. When A is treated with OsO₄ followed by aqueous NaHSO₃, an achiral compound D (a stereoisomer of C) forms. Identify all compounds, including stereochemistry where appropriate.
