Final answer:
NMR spectrum is used to obtain information about the number of neighboring hydrogens each hydrogen has.
Step-by-step explanation:
The information about the number of neighboring hydrogens each hydrogen has can be obtained from the NMR spectrum.
NMR (Nuclear Magnetic Resonance) spectroscopy is a technique used to study the arrangement of atoms, connectivity between atoms, and the number of hydrogen atoms in a molecule. It provides information about the chemical environment and bonding of hydrogen atoms in a compound.
By analyzing the NMR spectrum, the chemist can identify the peaks corresponding to different types of hydrogen atoms and determine the number of neighboring hydrogens around each hydrogen atom.
