The technique of ____ can be used to determine the chemical structure of a molecule.
A) HPLC
B) SEM
C) NMR
D) IR spectroscopy

Question

Quizplus · Accepted Answer

Nuclear magnetic resonance (NMR) spectroscopy is used to determine the arrangement of atoms in a molecule, as it gives information about the type and number of nuclei in a molecule and their chemical environment. Infrared (IR) spectroscopy is used to determine the functional groups present in a molecule based on the vibrations of its bonds. HPLC (high-performance liquid chromatography) and SEM (scanning electron microscopy) are not generally used for determining the chemical structure of a molecule.
