Compound a, c11h12o, which gave a negative tollens test, was treated with lialh4, followed by dilute acid, to give compound b, which could be resolved into enantiomers. when optically active b was treated with cro3 in pyridine, an optically inactive sample of a was obtained. heating a with hydrazine in base gave hydrocarbon c, which, when heated with alkaline kmno4, gave carboxylic acid d. identify compounds a, b, and c.
