Using the IR full scan, I have to determine the formula and the structure of the compound. I have attached the scans. Looking at the IR scan, I see that I have an NH and a CH. So is my compound CH2N?? I also have a mass spec output for an unknown organic compound. I have to determine the structure and formula. Using the CxHy rule, I have the following: 42= C3H6 50= C4H2 67= C5H7 81= C6H9 93= C7H9 107= C8H10 138= C11H6 I am not sure what to do after this...do I just write the formulas together and that is my answer??
