The number of unique carbons in a molecule will correspond to the number of signals in the 13C NMR spectrum. Identify the number of unique carbons in this structure. 4 unique carbons Tap here for additional resources

None

Identify the molecules and why you think it is the molecule.

How many signals would be in a CNMR AND HNMR for this product? Please explain in depth. H3C OH Z

No need explanation please correct answers need only

For the following spectra, IF A SPECTRA can be readily matched to a molecule do so and then indicate the absorptions on the spectra. For any spectra and molecules that can’t be easily assigned explain why, and also identify absorptions on the spectra.

First picture: use the C13NMR spectrum below to determine the structural formula for the compound of molecular formula C5H10O Second picture: picture: use the HNMR spectrum below to determine the structural formula for the compound of molecular formula C6H12O2

How many 07 9 8 6 ¹HNMR 23) Reset Answer signals will observe for (2-bromopropyl)benzene?

Applications of NMR spectroscopy in pharmaceutical analysis Can potentially be used for fingerprinting mixtures Has good potential for non-destructive quantitative analysis of drugs in formulations without prior separation Can determine impurities, including enantiomeric impurities, without separation Powerfull technique for the characterization og the exact structure of raw materials, intermediates, and finished products
