An organic compound having molecular formula C₉H₁₀O is supplied to a student to determine  the structural formula of compound. He observe that compound forms an orange red precipitate with 2.4 DNP reagent and yellow precipitate on heating with I₂/NaOH. It neither reduces tollens reagent or Fehling solution nor it decolorises bromine water solution. On drastic oxidation with CrO3, it produces a carboxylic acid having molecular formula C₇H₆O₂. Identify the correct compound A.
