IR Spectrum of Benzophenone and
Triphenylmethanol
I have partly labeled these two IR spectrums but need help
making sure I did it correct and if I need to label any other
important peaks corresponding to the structures. See underneath
each picture for the labeled peaks and if they are correct/if I
should label any others.
Benzophenone:
C-H stretch (aromatics) at around 3000-3100?
C=O strecth (ketone) at around 1700?
Any others that I missed that are important for me to label?...

Does a stronger peak in IR means anything? For example, I have an IR and is looking at 2 different peaks to see which one is the major product and minor product. Does stronger peak (deeper toward the bottom) mean more major product? or no? i.e. can you tell if a product is a major or minor product from looking at IR?

etc).

i have some questions about IR. my first one being I am anaylyzing an IR graph what are reasons for the frequency not lining up with literature values? secondly, why might an alkyl CH group not show up at all on an IR graph? and lastly, what do the different peak lengths mean? and why can you look at the same compound but on different graphs and have different peak lengths?

In the stretching region of the spectrum, identify as many IR peaks as possible that are consistent with the molecular formula. List the wavenumber of each identifiable peak and the type of bond or structural grouping to which it corresponds. Draw the structures of all possible molecules that are consistent with both the molecular formula and the stretching frequencies present in the IR spectrum. On the basis of all frequencies, both stretching and bending, ) state which structure(s) can be...

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
