Which peaks in your IR spectrum match the known structure of
caffeine? for each diagnostic peak, you should identify its
frequency in wavenumbers and the probable vibration (e.q 2950 cm,
alkane C-H stretch). You should then write a short discussion that
matches the diagnostic peaks to a functional group in caffeine
structure
Label all the function groups

Preparation of an a,b-unsaturated ketone via Michael and Aldol
reactions
The carbon next to the carbonyl (C=O) carbon is called the a
carbon and the carbon next to the a carbon is called the b carbon.
An a,b-unsaturated car- bonyl compound is a carbonyl compound
(aldehyde, ketone, ester, etc.) that has a multiple (double or
triple) bond between the a carbon and the b carbon.
As part of your post-lab report, analyze your spectra.

List all possible classes of compounds this compound could be. Does
it contain carbon-carbon double or triple bonds?
From the mass spectrum and IR, determine the molecular formula
and calculate the degree of unsaturation.

For my organic chemistry lab, we are supposed to identify all
significant peaks in each of the spectrums and label each “bond”
peak with its range in cm. I am really stuck and lost on this so
any help would be greatly appreciated.were also supposed to provide
