I need help solving Problem #12 and the subsequent (a-c) questions. Please help! I have no idea how to start.
2 . ( 16 points ) An unknown compound was found to have an m / z ratio of 1 13 0960 usingARMS with electrospray ionization . Assume that the compound was protonated and didnot rearrange , so you are measuring the M + HI peakHere are some possible M + HI formulas and massesCSHO113 .0233CSHIN31 13.0949COHO1 130597CH 13 01 13. 0962CHIEN1 13. 1200Ca HIT1 13 . 1326( a ) What is the correct formula for the unknown compound ?( b ) What is the unsaturation number for the unknown compound ?( C ) The IR spectra of the unknown compound is shown below120 0500 40Wavenumberlem – 1 1What can you conclude from the spectra ?
