Question “IR Spectrum of Benzophenone and Triphenylmethanol I have partly labeled these two IR spectrums but need…”
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?
Triphenylmethanol:
O-H stretch at around 3400-3500?
C-H strecth (aromatics) at around 3000-3100?
Any others that I missed that are important for me to label?
Answer
This concept is used to interpret the IR spectra for benzophenone or triphenylmethanol.
IR spectroscopy refers to the interaction of infrared radiation and the substances.
This method is used to identify functional groups within chemical compounds.
Each functional group has a unique absorption frequency.
The frequency of a vibration depends on the force constant, but is inversely proportional the mass of the atoms.
Take into account the IR spectrum for benzophenone.
stretching alkenes.
Strong, intense peak at corresponds with stretching.
The aromatic benzene rings are medium-intensity peaks at
Take a look at the IR spectrum for triphenylmethanol.
peak corresponds to stretching (free).
corresponds with alkyl #media_tag_8$ stretching.
The aromatic benzene rings are medium-intensity peaks at
Ans:
This is the interpretation of the IR spectrum for benzophenone:
This is
