Using infrared spectroscopy, how can salicylic acid be differentiated from acetylsalicylic acid (aspirin)? O 1) Acetylsalicylic acid and salicylic acid cannot be differentiated via IR spectroscopy as they have all the same stretches present. Acetylsalicylic acid will have two carbonyl (C-O) stretches at approximately O 2) 1700 cm1. It will possess one C=O stretch at about 1680 cm1 for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm 1 for the ester function. group. 3) Salicylic acid will have a unique aliphatic sp3-hybridized C-H at approximately 3150-3050 cm 1. Salicylic acid will have two carbonyl (C-O) stretches at approximately 1700 4) cm. It will possess one C=O stretch at about 1680 cm for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm for the ester functional group.

I'm about to have an organic chemistry test tomorrow and I don't fully understand the purpose of Mass Spectrometry. Can you please explain why it is used, is the molecule destroyed after (unlike IR spec), and any other useful details? I understand that IR spec is for identifying functional groups and together with NMR we can predict a likely compound.Where does mass spec come into play?Thank you!

p-dihydroxybenzene and o-dihydroxybenzene can be separated by TLC using a solvent of medium polarity. The ortho isomer has a significantly higher Rf value than the para isomer. Suggest a reason for this difference in Rf values. (hint- consider the structure of these two molecules)
In UV spectroscopy we are taught the effects of polarity on liquid chemistries that may undergo bathochromic red shif, hypochromic blue shift , hypsochromic decrease in absorbance and aborptivity and hyperchromic effects a increase in absorbance or absorptivity. The cause for hyperchromic shifts has one explanation that appears to make sence and that is related to Auxochromic groups or the effect on the chromophore for for a new chromophore with the auxo group that causes both a hyperchromic and bathochromic red shift. Question 1: Does this dual shift in absorbance and wavelength occur in non-liquid sustances like plastics e.g. polypropylene, polyethylene, condensation polymers like PET and Polycarbonate? Question 2: Is there a way to predict level of hyperchromic shift based on the auxochromic group or do we need to know the chromophore? Question 3: Are there known examples of chromophore and Auxochromic groups that provide various molar extinction or absorptivity or absorbance…
