Identify the incorrect statement:

Identify the incorrect statement:Identify the incorrect statement:

Options

  1. AThe S−S−SS-S-S bond angles in the S8S_{8} and S6S_{6} rings are the same.
  2. BRhombic and monoclinic sulphur have S8\mathrm{S}_{8} molecules.
  3. CS2\mathrm{S}_{2} is paramagnetic like oxygen
  4. DS8\mathrm{S}_{8} ring has a crown shape.

Correct answer

A. The S−S−SS-S-S bond angles in the S8S_{8} and S6S_{6} rings are the same.

Step-by-step solution

The S6\mathrm{S}_{6} molecule has a chair-form hexagon ring with the approx same bond length as that in S8\mathrm{S}_{8}, but with some what smaller bond angles i.e. bond lengths are approx same but bond angles are different. Identify the incorrect statement:
