An organic compound X with molecular formula ${\mathit{C}}_{11}{\mathit{H}}_{14}$ gives an optically active compound on hydrogenation. Upon ozonolysis, X produces a mixture of compounds – P and Q. Compound P gives a yellow precipitate when treated with ${\mathit{I}}_2$ and NaOH but does not reduce Tollen's reagent. Compound Q does not give any yellow precipitate with ${\mathit{I}}_2$ and NaOH but gives Fehling's test. The compound X is :
