A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the following Lewis structure and what you know about VSEPR theory, identify the shape. Tetrahedral linear T-shaped trigonal bipyramidal square ...SeO2 crystallizes in the orthorhombic Pbam space group. The structure is one-dimensional and consists of four SeO2 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is one shorter (1.64 Å) and two longer (1.85 Å ...Chemistry questions and answers.

Such studies as on the glasses or glass ceramics mixed with relatively large concentration of SeO2 are very rare in spite of their high suitability for the several applications for example, in electrical and optical devices as sensors and various non …Below is the image of the incorrect lewis structure of SeO2. Now, when we calculate the formal charge distribution for the correct Lewis structure of selenium dioxide using the aforementioned formula, the total is amounting to zero [The diagram of the correct Lewis structure is already shown above in this article].

Sulfur dioxide, or SO_2, has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO_2 which is more stable in theory, but doesn't quite match experimental data. Let's draw the first two Lewis structures for SO_2. The Lewis structure of SeO2 consists of a selenium (Se) atom at the center. It is double-coval
