In the 1H NMR spectra of 2-bromopropane (CH3)2CHBr and 1-bromopropane CH3CH2CH2Br, how many signals do you expect to see?
Following is a 1H-NMR spectrum of 2-butanol. Explain why the CH2 protons appear as a complex multiplet rather than as a simple quintet.
You have an unknown with an absorption at 1680 cm-1; it might be an amide, an isolated double bond, a conjugated ketone, aconjugated aldehyde, or a conjugated carboxylic acid. Describe what spectral characteristics you would look for to help youdetermine which of these possible functional groups might be causing the 1680 peak.
