Identify the incorrect statement :

Options

  1. AThe S-S-S bond angles in the S 8 and S 6 rings are the same.
  2. BRhombic and monoclinic Sulphur have S 8 molecules.
  3. CS 2 is paramagnetic like oxygen.
  4. DS 8 ring has a crown shape.

Correct answer

A. The S-S-S bond angles in the S 8 and S 6 rings are the same.

Step-by-step solution

Sulphur have puckered S 8 rings with crown conformation, and S 6 rings arranged in a chair conformation. 1) S-S-S bond angles in S 8 and S 6 rings are different 2) Rhombic & monoclinic are S 8 molecules but the arrangement of the molecules in space are different. 3) S 2 & O 2 both are paramagnetic according to MOT
