Can you please help me answer the following questions please. I
really need them all and I will rate
2. Select the NMR spectrum that corresponds best
to p‑methoxybenzaldehyde. All spectra are taken
in CDCl3 and the peak at 0.0 ppm is trimethylsilane, which is
used as a standard to calibrate chemical shifts.
The matching NMR spectrum is:
The boxes are labeled by ranges within the infrared spectrum, representing the wavelengths at which specific functional groups absorb energy. The scale is shown in wavenumbers, cm. Classify each functional group according to the approximate range where it would produce a stretch on the spectrum. Note: The stretches of the functional groups may not fill the entire range. 3700-3200 cm 3200–3000 cm- 2500-2000 cm- 3000-2500 cm-! 2000-1800 cm - -1 1800-1600 cm- Answer Bank CEC alkyne C-O aldehyde 0-H alcohol C-H aromatic
