Hi guys, I have a chemistry question which has been disturbing me. Please help me, it goes like this. A liquid, C6H12O2, was hydrolyzed with water and acid to give an acid A and an alcohol B. Oxidation of B with chromic acid produced A. The formula of the original compound is? I will attach the image for the choices since I have no idea how to turn the following compounds in a linear equation Choice A which is highlighted in yellow was the answer provided. http://imgur.com/iBtgRFI Could you please explain why the Choice A is the answer because I'm quite confused thinking that Choices A, B, and C are all possible answers because there is a carbonyl group. If you may also please include why choice D is not the answer? Help will be appreciated.
