Which type of radiation is used in MASS spectrometry? infrared light ultraviolet light radio waves none In which region would you look for C=O stretching modes? 3500-3400cm^-1 3300-2800cm^-1 2300-2100cm^-1 1800-1600cm^-1 Which area of the IR spectrum is called the finger print region"? 4000-2800cm^-1 2800-2000cm^-1 2000-1400cm^-1 1400-600cm^-1 What is the "base peak generated from 1-methylcyclohexene? 81 86 15 96 What kind of functional group does have a right connection in a IR spectrum? amine with N-H at 3000 cm^-1 nitride group at 1700 cm^-1 carbonyl group at 3500 cm^-1 aldehyde group at 2700 and 2800 cm^-1 In what region of the H-NMR spectrum would you expect to have a signal for the-CH_3, (methyl group) of methylphenylether, CH_3OH_3H_3 0-2 ppm 3-4 ppm 5-6 ppm 7-8 ppm Nitrogen gas, N_2, has no absorption while carbon dioxide, CO_2, has one in IR spectroscopy, since oxygen is more electronegative than nitrogen since nitrogen gas has no dipole moment change in its vibration. since carbon dioxide has double bonds, not triple bond. since nitrogen gas is an inert in any reaction. In the following mass spectrum, which element should be presented in the molecule? Bromine Chlorine Iodine Nitrogen Sulfur How many different NMR signals produced from 2.2-dimethylbutane in^13c NMR? 4 signals 3 signals 2 signals 3 signals Which radiation is higher in energy relatively? microwave visible radio-wave infrared Spin-Spin splitting is used for finding some information about number of hydrogen contributing to that peak in HNMR number of hydrogen contributing to the neighboring^13CNMR number of hydrogen which has a three-bond distance to that peak in^1H NMR number of hydrogen which is closed in the space not through the bonds in^1H
