Default Answered: help with chemical shifts and NMR in Organic Chem?
What would my skeletal structure look like if I have C4 H7 ClO2Singlet @ 6.17 ppmQuartet @ 2.29 ppmTriplet @1.14 ppmPlease help....I'm new at this and have homework due in a few hours...the professor kind of put us on a crash course and the text does not help much!Thanks for anything you can contribute

CH3CH2CO2CH2ClEven though you left off the integral, this will work. Triplet and quartet means two and three adjacent hydrogens. That means there are two hydrogen left to place on a single carbon, a CH2. It must be attached to an oxygen because it is shifted so far downfield. No more hydrogens and a missing C=O group. Place it between the CH2 and the OCH2Cl.
