What makes an amine peak different than an alcohol peak, in infrared spectra?

Which analytical instrument is used primarily to determine the functional groups present in a compound?

An organic chemist begins to analyze an ifrared (IR) spectrum. He immediately notices a strong, sharp peak at . This peak is most likely present in the spectrum due to which of the following functional groups?

Rank the following IR bond resonances in order of increasing frequency:

sp3, sp2, , ,

A compound was analyzed using the TLC plate above in diethyl ether. The TLC plate is 60 mm long and the compound was spotted 5 mm from the bottom of the plate. The solvent was allowed to travel up the plate until it was 5 mm from the top. If the compound traveled a total of 15 mm, what is the Rf of this compound?

An organic chemist began analyzing an infrared (IR) spectrum. She noticed a strong, sharp peak at around and a strong, broad peak at around . Which functional group(s) correspond(s) to the data provided by the IR spectrum?

Which of the following spectroscopic techniques provides the most information about an organic molecule's framework/structure?

Thin layer chromatography (TLC) is being used to separate a crude mixture of the following compounds using a 3:1 hexanes:acetone. What would be the order of the compounds on the TLC plate once run, highest Rf to lowest Rf?

Why is the mass spectrometry a useful method in laboratory practice?

The starting compound used in a reaction, which proceeds by a SN1 mechanism, has an optical rotation of . What is the expected optical rotation of the product? (Assume the substitution occurs at the chiral center.)
