BITSAT Chemistry Question (2021) — Solution
Options
- 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
A. The S-S-S bond angles in the S_ 8 and S_ 6 rings are the same.
Step-by-step solution
The S _ 6 molecule has a chair-form hexagon ring with the approx same bond length as that in S _ 8 , but with some what smaller bond angles i.e. bond lengths are approx same but bond angles are different.
