Unknown Identification via Spectroscopy Wendy Mei Tuesday 6pm-915pm Grade Sheet Predicted Structure of Unknown Calculated Index of Hydrogen Deficiency: C-H/2-X/2+N/2+1= 5-6/2-0+0+1= 3 This number shows that there is a ring and two double bonds in the structure of this molecule because the ring is equal to one degree of unsaturation and the two double bonds count as one degree of saturation each. Mass Spectroscopy The molecular weight of the compound is 114g/mol, displayed by the last peak shown at 114m/z. The different numbers listed above each of the peaks represent separate parts of the compound. For example, 15m/z usually represents a CH 3 and 86m/z represents C 4 H 6 O 2 .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
