The two isomeric alcohols W and X each have the molecular formula $\text{C}_4\text{H}_9\text{OH}$. When W is oxidised, it forms carbonyl compound Y, and Y produces a red precipitate with Fehling's solution. When X is oxidised, it forms carbonyl compound Z, and Z does not produce a red precipitate with Fehling's solution. Which of W and X forms a yellow precipitate with alkaline $\text{I}_2$(aq)?
