Vedclass · Answer

(B) Sulphur exists in various allotropic forms like $\alpha$-sulphur (rhombic) and $\beta$-sulphur (monoclinic),which consist of $S_8$ puckered ring structures. These forms are diamagnetic because all electrons are paired in the $S_8$ molecules.The $S_2$ form of sulphur is analogous to $O_2$ and is paramagnetic in the vapour state at high temperatures due to the presence of two unpaired electrons in its antibonding $\pi^*$ molecular orbitals.Therefore,only the $S_2$ form shows paramagnetism.The number of such allotropic forms is $1$.

Among the following allotropic forms of sulphur,the number of allotropic forms,which will show paramagnetism is ..... .
$(A)$ $\alpha$-sulphur
$(B)$ $\beta$-sulphur
$(C)$ $S_2$-form
