    Very confused on combo structure problem (given IR,HNMR,MS)

    Hello All, I am in serious trouble here with this structural determination. I am given IR, HNMR, and MS (with a CI (methane) MS). Here's where I am at: I know it must be a Carbox' Acid judging by the IR and characteristic Base Peak at 60 amu and 1 H at ~11ppm. The thing is I can't come up with...
