Among the following allotropic forms of sulphur, the number of allotropic forms, which will show paramagnetism is ________. (A) α-sulphur (B) β-sulphur (C) S2-form (D) None of these

1. α-sulphur
2. β-sulphur
3. S2-form
4. None of these

Correct answer: α-sulphur

Solution

α-sulphur is the only allotrope that exhibits paramagnetism due to the presence of unpaired electrons in its molecular structure, allowing it to be attracted to a magnetic field.
