Verified Answer
Which of the following spectroscopic techniques provides the most info...
- NMR spectroscopy is most useful for determining the type of nuclei (most commonly studied nuclei are 1H and 13C) present and their relative locations within a molecule. H-NMR is most commonly used because it is practically present in all organic compounds.
- This technique is useful for a complete determination of the structure of organic compounds. IR spectroscopy is best for determining the functional groups of a molecule, however, it does not give information of the electric environment like NMR.
- Mass spectrometry is a technique used to determine the amount and mass of substances present in a sample. UV-visible spectroscopy is used to determine the amount of analyte present in a given sample - this method is best for transition metals and/or highly conjugated compounds.
- Melting point analysis gives information about the purity of a sample, pure substances tend to have higher melting points and more narrow ranges than impure samples.

NMR Spectroscopy for Organic Molecules
NMR spectroscopy is the spectroscopic technique that provides the most information about an organic molecule's framework and structure. Here's why:
Structural Information:
- NMR spectroscopy provides detailed information about the connectivity of atoms in a molecule. It can determine the types of atoms present, the number of each type, and their spatial arrangement within the molecule.
- By analyzing the chemical shifts and coupling patterns in an NMR spectrum, chemists can deduce the functional groups present in the molecule and their relative positions.
Isomer Differentiation:
- NMR spectroscopy can distinguish between different isomers of a compound. Isomers have the same molecular formula but different structural arrangements, and NMR can differentiate between them based on their unique spectral features.
Conformational Analysis:
- NMR spectroscopy can also provide insights into the conformation of a molecule in solution. By studying the coupling constants and peak intensities in the spectrum, chemists can determine the preferred conformations of the molecule.
Quantitative Information:
- NMR spectroscopy can also provide quantitative information about the concentration of different species in a mixture. By integrating the peaks in the spectrum, chemists can determine the relative amounts of each component present.
In conclusion, NMR spectroscopy is a powerful tool for elucidating the structure of organic molecules due to its ability to provide detailed structural information, differentiate between isomers, analyze conformational preferences, and offer quantitative data about the composition of a sample.
