MCQ
Spin isomerism is shown by
  • A
    dichlorobenzene
  • ✓
    hydrogen
  • C
    dibasic acid
  • D
    $n-$ butane
✓

Answer

Correct option: B.
hydrogen
b
Spin isomerism is shown by hydrogen. In ortho-hydrogen, the spin of nuclei of two atoms of the molecule are in same direction whereas in case of para hydrogen, the spin of nuclei of two atoms are in opposite direction.
