- please help me with also using correct sig figs and labelling units. #1Identify the unknown compounds A, B, C, D and E based on their IR spectra (see below) from the following list and provide a sentence or 2 explaining why : · 1-propanol · hexane · benzyl alcohol · 1-hexanol · ethyl benzoateOrganic Chemistry: IR spectroscopy A student obtains an IR spectrum with an intense, broad absorption at about 3350 cm-1. The student claims that the sample is an alcohol, but the professor says that the absorption is there because the sample is contaminated with water. What peak(s) could be looked for to show that the sample is indeed an alcohol? Which functional groups would make it difficult to use this strategy?
- show your work for the determination of the Ksp of sodium chloride for your samplep-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)( give detail explantion behind choosing this value )
- Draw the fragmented molecular ion for the compound shown above for peaks 127,144 and 159. Thank you.Interpet and analyze this Infrared (IR) spectra to show the signs from the peaks and what they tell about the unknown compound.A common lab experiment is the dehydration of cyclohexanol to cyclohexene. Explain how you could tell from the IR spectrum whether your product was pure cyclohexene, pure cyclohexanol or a mixture of both. Give approximate frequencies for distinctive peaks.
