Upon completing a reaction in the lab, you determine the percent yield for the process to be 140%. Obviously, something isn't right. You double check your math and everything is good from that end. You take a melting point, which is close to the literature value. You take an IR and notice an extra strong signal at 1700 cm-1 that doesn't match what you would expect on your compound. You don't notice a broad signal above 3000 cm1. Of the possibilities, which would be the most probably given your elevated yield? The sample wasn't sufficiently dried and has water in it. You recall that you washed the sample with acetone. You must not have evaporated all of the acetone away. O Your sample has an impurity from the reaction. O You only weighed out 90% of your isolated compound.

Identify the spectra. All pertinent peaks must be assigned on spectrum (5-6 peaks). Label the peaks on spectrum. I have provided the correct structure in the lower left hand corner, I just need help with labeling the peaks on the spectrum to match the structure.
Determine the formula of the hydrocarbon compound where m/z=134. The mass spectrum indicates an M+2 peak in a 3:1 ratio. The IR spectrum also indicates a strong peak at 1760 cm1 Answer:
ORGANIC CHEMISTRY QUESTION Below is the mass spectrum for 1-(chloromethyl)-2-methylbenzene. The mass of the molecular ion is 140 m/z. Annotate the spectra with any and all relevant signals. This includes but is not limited to the base peak, molecular ion peak, key fragments, and other isotopic signals of relevance.Each annotation should be clearly marked and include the m/z.
The mass spectrum of an unknown compound has a molecular ion peak with a relative intensity of 52.18% and an M+1 peak of 3.37%. How many carbon atoms are in the compound? (Fill in an integer number)

2. In a mass spectrum of a compound, the following data (intensity) is given. M+ = 80, M+ +1 = 8.8, M+ +2 = 26. This compound will have carbons and will contain a a. 8, sulfur b. 9, silicon c. 10, chlorine d. 11, bromine
Below are three MS spectra, Spectra 1, 2, and 3. Each of this mass spectrum corresponds to either Compound A (contains one Cl in the molecular formula), Compound B (one I in the molecular formula), and Compound C (one Br in the molecular formula). Identify which spectra corresponds to which compound. Provide explanations for your choices.
List the most significant peaks in each region, then their interpretation.
Shown below are the IR spectrum and the Mass Spectrum of a compound of molecular formula C3H8O. Using the spectral data, determine the structure of the compound. Provide evidence from both spectra to support your answer.
A researcher is studying cytochrome oxidase, a protein that uses iron to bind diatomic oxygen. She collects two IR spectra, shown below. In the first spectrum, no isotopic labeling is used (top). In the second, 160 has been replaced with 180 (bottom). 820 655 790 0.5- 714 695 733 820 655 755 0.5- 714 695 733 0- 600 650 700 750 800 850 Vo (cm") Based on the above ratio, which is the most likely source of this vibration, (a) the Fe-O stretch in Fell-O=0, or (b) the O-O stretch in Fell-O=O?
