2. (6 points) When 2-bromoacetophenone and benzaldehyde are treated with the same condition as Aldol condensation (shown below), an interesting product is formed. Br NaOEt 2-bromoacetophenone 1) Deduce the structure of the product based on its data. Molecular formula: C18H12O2, IR: a peak at 1710 cm-1, 'H NMR: 4.08 ppm (doublet, 1H), 4.30 (doublet, 1H), 7.48-8.02 (multiplet, 10H). 2) Provide a mechanism for this reaction.
We performed an aldol condensation reaction using
4-bromoacetophenone and benzaldehyde. How can I prove this with the
IR spectra we obtained? What are the stretches I should note to
prove that we obtained
(E)-1-(4-bromophenyl)-3-phenylprop-2-en-1-one as our product and
benzaldehyde as our aldehyde?

When 2-bromo-3,3-dimethylbutane is treated with K+ −OC(CH3)3, a single product T having molecular formula C6H12 is formed. When 3,3-dimethyl-2-butanol is treated with H2 SO4, the major product U has the same molecular formula. Given the following 1H NMR data, what are the structures of T and U? Explain in detail the splitting patterns observed for the three split signals in T.1H NMR of T: 1.01 (singlet, 9 H), 4.82 (doublet of doublets, 1 H, J = 10, 1.7 Hz), 4.93...

An aldol condensation reaction was performed where benzaldehyde
and cyclopentanone were used. The product is 2,5
dibenzylidenecyclopentanone or just 2-benzylidenecyclopentanone.
The spectra correspond with the aldehyde being benzaldehyde but the
ketone used could either be acetone, cyclopentanone or cyclohexane.
I need to find the NMR spectra that correspond to cyclopentanone
being the ketone in the aldol condensation. Which NMR spectra
correspond to the correct product?
I think the second set is with cyclohexanone and not
cyclopentanone but I could be...
Problem #23: When compound X (C,H,Br) is reacted with sodium cyanide (NaCN) forms compound Y (C,H,N). Compound Y, upon reduction with H over a Ni catalyst, yields compound Z (C,HIN. The 'H NMR spectrum of X gives two signals, a multiplet at δ = 7.3 ppm (5H) and a singlet at δ 4.25 ppm (2H). The 'H NMR spectrum of Y is similar to that of X in that it shows a multiplet at ö-7.3 ppm (5H) and a singlet...
This experiment was based on Aldol-dehydration reaction using
unknown aldehydes and ketones. We carried out an aldol condensation
between an unknown aldehyde and an unknown ketone. Here are the
list of possible unknown aldehydes and ketones that were used.
Here is the NMR of the final product. Please predict the
structure given the melting point is 163 degrees Celsius.
The analysis of the 1H NMR spectrum should include a detailed
assignment of each of the NMR resonances to the protons...
all three numbers please
