The number of SS bonds in sulphur trioxide trimer (S3O9) is 0.
Explanation:
- sulphur trioxide trimer (S3O9) is composed of three sulfur atoms (S) and nine oxygen atoms (O).
- In this compound, each sulfur atom forms a double bond with one oxygen atom, resulting in three S=O bonds.
- However, there are no SS bonds present in the compound.
Reasoning:
- A single bond is formed when two atoms share one pair of electrons, while a double bond is formed when two atoms share two pairs of electrons.
- In the case of the S=O bonds, the sulfur atom shares two pairs of electrons with the oxygen atom, resulting in a double bond.
- However, there are no sulfur atoms that share pairs of electrons with each other, leading to the absence of SS bonds in the compound.
Conclusion:
- The presence of double bonds between sulfur and oxygen atoms does not imply the presence of SS bonds within the compound.
- In the case of sulphur trioxide trimer (S3O9), there are three S=O bonds but no SS bonds.
