MCQ
In 1H NMR, what does the chemical shift (delta) value indicate?
Chemistry
A Number of equivalent protons
B The electronic environment of the proton
C The number of neighboring protons
D The molecular weight
Explanation

Chemical shift reflects the shielding/deshielding of a proton by surrounding electrons. Deshielded protons (near electronegative atoms) appear at higher delta values.
