1. The problem statement, all variables and given/known data Which of the substances below is least soluable in water? A. CH2OHCHOHCH2OH B. CH3COCH3 C. CH3CH2COOH D. CH3COOCH3 2. Relevant equations 3. The attempt at a solution I think bith B and C are not possible since B can dissolve in water easily and C is acid which is soluable in water. But i don't know what to choose from A and D. I checked on the Internet, it says D is not easy to dissolve in water, but my teacher told me he thinks A or B will be the answer. I totally think he is wrong at this point. Can anyone help me out with this?
