Answer» An unknown organic compound (A) with the molecular formula $C_{9} H_{12} O$ does not decolourize $B r_{2}$ in $C C l_{4},$ reacts with sodium to give a colourless, odourless gas and can be oxidised by hot alkaline $K M n O_{4}$ to give benzoic acid. Then, following test were performed on the compound (A) is given sequence: Test (a): The colour of the solution changes from orange to green when $K_{2} C r_{2} O_{7}$ is added to it. Test (b): The compound can be resolved. Test (c): No yellow precipitate of $C H l_{3}$ is formed when reacted with $l_{2}$ and $O H^{-}$ . Test (d): Oxidation of the compound with $C r O_{3}$ in pyridine gives another compound that gives Tollen's test. The structure assigned to compound (A) after the test (d) would be
