Question

Identify the incorrect statement :

• A. The S-S-S bond angles in the $S_8$ and $S_6$ rings are the same.
• B. Rhombic and monoclinic Sulphur have $S_8$ molecules.
• C. $S_2$ is paramagnetic like oxygen.
• D. $S_8$ ring has a crown shape.

Answer 1

Answer: (A)

Sulphur have puckered S₈ rings with crown conformation, and S₆ rings arranged in a chair conformation.

1) S-S-S bond angles in ${\text{S}}_8$ and ${\text{S}}_6$ rings are different
2) Rhombic & monoclinic are ${\text{S}}_8$ molecules but the arrangement of the molecules in space are different.
3) ${\text{S}}_2$ & ${\text{O}}_2$ both are paramagnetic according to MOT
