What would you expect to see in the UV spectrum of the following molecule? Graph your answer and label absorption bands. You don't need to provide specific wavelengths but please explain your answer. [10 pts] он
how many peaks in an IR spectrum would you expect to see that would characterize an alcohol functional group
how many peaks in an IR spectrum would you expect to see that would characterize a carboxylic acid functional group?
a. Sketch the expected shape of the pure vibrational absorption spectrum of a diatomic molecule that is well described by the harmonic oscillator model (absorbance as a function of frequency). (We are pretending that there are no rotations occurring for this question. For real diatomic molecules, if they are IR active, there will also be rotational excitations and therefore a rovibrational spectrum.) In what portion of the electromagnetic radiation spectrum would you expect this absorption to occur? b. Sketch the...
Draw the structure of the compound you would expect from SN2
reaction of the molecule below with NaCN.
Use the wedge/hash bond tools to indicate stereochemistry.
Include H atoms at chiral centers only.
If a group is achiral, do not use wedged or hashed bonds on
it.
You may use the OWL references to look up acidities if you want
to compare leaving groups.
