Select the true statement about chemically equivalent hydrogen atoms in ^1H NMR spectroscopy. Their signals tend to absorb relatively far upfield. All of their nuclear spins are aligned in the same direction. Their signals are not split by other hydrogen atoms. They have the same chemical shifts.
Expert Answer
Chemically equivalent hydrogen s have the same chemical shift values because the electronic environment around the two hydrogens is same.
Chemical shift values depends on the electronic nature around the hydrogen atom. If that electronic nature is same then their chemical shifts will be same.
Option A is wrong as chemically equivalent proton may be at low field or down field depending on the electronic nature around hydrogen s.
Option. B is also wrong all the spins are in same direction.
Option C is wrong as those hydrogens are split by the adjacent hydrogens . Option D is correct.
