To work out the functional groups of an organic molecule, you would look at its? A. proton NMR spectrum B. mass spectrum C. IR spectrum D. boiling point A substance contains a component A with (λmax = 502 nm) and a component B with (λmax = 670 nm). Which one of the flowing techniques could be used for separation and detection of these two components in this substance, after a suitable sample preparation? A. HPLC with UV detection B. AAS C. HPLC with UV-VIS detection D. None of the above Read more

Understand the Problem

The question is asking which techniques can be used for detecting and separating two components in a substance, based on their maximum absorption wavelengths. It also inquires about how to identify the functional groups of an organic molecule using corresponding spectral techniques.

More Information

IR spectroscopy is key for identifying functional groups due to their specific vibration frequencies. HPLC with UV-VIS is versatile for detecting diverse compounds based on their specific light absorption properties.

Tips

A common mistake is assuming NMR or mass spectrometry is best for functional groups; however, IR is specialized for this purpose.
