Which of the following exists as a cyclic tetramer in the solid state?

Options

A. `SO_(3)`
B. `SeO_(3)`
C. `TeO_(3)`
D. `PoO_(3)`

Answer

2

Explanation

`SO_(3)` in the gas phase exists as planar triangular molecules species.In the solid state, `SO_(3)` exist in serveral modification having a linear cyclic trimetric or a polymeric chain structure.On the other hand ,`SeO_(3)` exists as a cyclic tetramer `(Se_(4)O_(12))` in the solid state`TeO_(3)` is also a solid with a network structure in which `TeO_(6)` octahedral share all vetices.
