Options

  1. AThe S-S-S bond angles in the S8{S}_{8} and S6{S}_{6} rings are the same.
  2. BRhombic and monoclinic Sulphur have S8{S}_{8} molecules.
  3. CS2{S}_{2} is paramagnetic like oxygen.
  4. DS8{S}_{8} ring has a crown shape.

Correct answer

A. The S-S-S bond angles in the S8{S}_{8} and S6{S}_{6} rings are the same.

Step-by-step solution

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

Identify the incorrect statement :
1) S-S-S bond angles in S8{\text{S}}_{8} and S6{\text{S}}_{6} rings are different

2) Rhombic & monoclinic are S8{\text{S}}_{8} molecules but the arrangement of the molecules in space are different.

3)S2{\text{S}}_{2} & O2{\text{O}}_{2} both are paramagnetic according to MOT
