The data is for the molecular formula C8H8O3 (vanillin) with a mass of 152. Analyze the Mass spec data (include a table listing the molecular ion, base peak, and any other relevant fragments) – also include structures of fragments.

which of the following statements is incorrect? A. a conventional mass spectrometer does not use a spectrophotometric detectorB. a conventional mass spectrometer does not always require high purity samplesC. a mass spectrum shows no signals due to uncharged speciesD. a conventional mass spectrometer uses high energy UV radiation

In the mass spectra below, determine the Base Peak, the molecular ion peak and indicate the fragmentation process of ions marked with their respective value. 100 Mass Spectrum CH3 105 80 60 40 M 134 20 C3H100 40 80 120 160 200 240 280 m/e 100- 80 91 Mass Spectrum 60 134 40 20 149 C10 H15N 40 80 120 160 m/e 200 240 280 % of bese peak % of base peak

Please don't provide hand wriitten solution....

Help figuring out how to solve to find the molecule. Please include work, thank you!

Consider the mass spectrum below. 100 80- 60- 20 0.0- 0.0 60 100 miz SDBS, National Institute of Advanced Industrial Science and Technology Which peak is the molecular ion? Choose one OA OB OD. OG

You have analyzed Fe2+ in a dietary supplement Hemofer with VIS spectroscopy and obtained the following results, see table 1. A total of 10 tablets have analyzers. Quantify the amount of Fe2+ mg and state with 98% confidence interval. Make sure to include all steps required in the quantification calculation. Also test statistically! Evaluate your result. Did you get a good result or not?, Did something go wrong and if so what could be the reason? Use analytical and statistical concepts. Nutritional information per tablet Iron 13.5 mg Vitamin C 40 mg

1. The mass spectrum of 3-hexanol is given below. 100 Intensity 55 80- 60- 40 40 20 20 59 73 3-Hexanol El MW = 102 OH 0 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 m/z (a) Rationalize the small size of the molecular ion peak at m/z 102. (b) Assign structures to all the labeled species and rationalize their formation.

I know the answer is D, but I dont know why. Can you cleave anywhere on the molecule, or only on certain areas? not certain of the rules. Is abundance the m/z (molar mass) of the molecule? I calculated 102 for the molar mass , but that is not one of the options to choose as an answer. Please explain plainly
