Compound X, $\text{C}_5\text{H}_{12}\text{O}$, undergoes oxidation with acidified sodium dichromate(VI) to form compound Y. Compound Y is then reacted with butan-2-ol, with a small amount of concentrated sulfuric acid present, to produce liquid Z. Give one possible formula for Z.
- A$\text{CH}_3(\text{CH}_2)_3\text{CO}_2\text{CH}(\text{CH}_3)\text{CH}_2\text{CH}_3$
- B$\text{CH}_3(\text{CH}_2)_3\text{CO}_2(\text{CH}_2)_3\text{CH}_3$
- C$\text{CH}_3(\text{CH}_2)_2\text{CO}_2\text{CH}(\text{CH}_3)\text{CH}_2\text{CH}_3$
- D$(\text{CH}_3)_2\text{CHCH}_2\text{CO}_2\text{C}(\text{CH}_3)_3$
