    how was chem p41 ??!?! expected thresholds ?!?!

    oh yeah that was a crazy question! i got it at the last minute! for C8H15... it had CH3-C=O and NH2 and carboxyllic acid end and CH2 in between for C4H5NO3 it had carboxyllic acid end, and CH3-C=O and for C4H7NO it had -OH (secondary alcohol), -CN in it and for the last one i dont remember... :D
