Ortho and Para hydrogen differ in-

Ortho and Para hydrogen differ in- Correct Answer Spin of their p<sup>+</sup>

CONCEPT:

  • The relative position of substituents in double-substituted benzenes is indicated by the prefixes ortho (o), meta (m), and para (p). 


EXPLANATION:

  • The ortho and para hydrogen differ in the nature of the spin of protons.
  • In ortho hydrogen, the spin of the proton is in the same direction.
  • But in para-hydrogen, the spin of the proton is in opposite direction in hydrogen molecules.
  • Hence option 3 is correct.
