Please also tell me why you picked the your answer. Show any sources used.

Select the FALSE statement about the molar absorptivity coefficient (epsilon). has higher magnitude for transitions from Pi electrons than from non bonding electrons it can be found from the slope of the linear part of the calibration curve (defined by the Lambert Beer law) for a specific compound it can be affected by the solvent used to dissolve the study compounds It is not affected by the wavelength used to irradiate the sample Which of the following factors will never affect the intensity of the absorption from a chromophore group in UV-Vis spectroscopy the height (the longest dimension) of the cuvette the pH the number of molecules containing the chromophore exposed to the radiation the population of the electronic states Select the TRUE statement about infrared spectroscopy. electronic transitions are the origin of the absorption bands observed in the IR spectra more than one absorption band may result when irradiating an analyte the absorption spectra is independent from the structure of the analyte hydrogen bonding never affects the spectra of a molecule Which of the following compounds will NOT absorb infrared radiation? carbon dioxide acetone chlorine chloroform In gas chromatography-mass spectrometry, the signal obtained can only be from which ONE of the following? charged species molecules with a chromophore group molecules which have a change in dipole moment during a vibration molecules that do not interact with magnetic field

Explanation / Answer

14) Among the given statements option A) is correct as nonbonding electrons are having higher magnitude.

15) The pH of the solution never affects the intensity of the solution, hence the answer is B)

16) Option B) is correct

17) Cl2 (due to absence of polarity)

18) Option A) is correct.
