Interpretation:
The number of expected
Concept introduction:
In order to determine the number of chemically distinct carbon atoms in a molecule, we can apply the chemical distinction test by substituting an imaginary atom X for each carbon atom. Then, we determine the relationship among those structures. If they happen to be constitutional isomers, then the carbon atoms are dinstict. If they happen to be identical, then the carbon atoms are identical.

- Determine the number of expected signals for the following compounds. (see picture attached).arrow_forwardIntrpt as many of the main peaks in the following spectra as you can – do this by providing the chemical formula of the species responsible for the peak in each casearrow_forwardTwo signals appear in the 1H NMR spectrum of thecompound shown here. One has twice the integration ofthe other. The signal with greater area corresponds to achemical shift of 9.3 ppm. The signal with less areacorresponds to a chemical shift of -2.9 ppm. Explain.Hint: Consider the magnetic field lines from a ring currentarrow_forward
- Solve correctly please. Match the chemical shifts in the 1H NMR spectrum with the given proton groups a-e for the following molecule: Options given below imagearrow_forwardChoose the molecule to which each of these two IR spectrums correspond (one possible answer per IR spectrum).arrow_forwardH NMR for molecule in the figure attached will show.. 7 signals. 6 signals. 4 signals. 3 signals. Other 5 signals.arrow_forward
