(I) Both \[\alpha \]-sulphur (yellow rhombic) and \[\beta \]-sulphur (monoclinic) consist of Sg puckered ring having crown shapes. |
(II) Below 369 K, monoclinic sulphur is more stable. |
(III) \[\varepsilon \]-sulphur or EngeFs sulphur consists of \[({{S}_{6}})\]6-membered puckered rings with chair form. |
(IV) In vapour state sulphur partly exists a \[{{S}_{2}}\]molecule and exhibits diamagnetism. |
A) II, III
B) I, III
C) I, II, III
D) II, III, IV
Correct Answer: B
Solution :
[b] Statements (I) and (III) are CORRECT. CORRECT statement (II): Below \[369\text{ }K,\]rhombic sulphur is more stable. CORRECT statement (IV): \[{{S}_{2}}\] exhibits paramagnetism, due to 2 unpaired \[\bar{e}'s\] in the antibonding \[\pi *\] orbitals.You need to login to perform this action.
