[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
The molecule SO 3 is trigonal planar.As predicted by VSEPR theory, its structure belongs to the D 3h point group.The sulfur atom has an oxidation state of +6 and may be assigned a formal charge value as low as 0 (if all three sulfur-oxygen bonds are assumed to be double bonds) or as high as +2 (if the Octet Rule is assumed). [7]
The structure of the sulfite anion can be described with three equivalent resonance structures. In each resonance structure, the sulfur atom is double-bonded to one oxygen atom with a formal charge of zero (neutral), and sulfur is singly bonded to the other two oxygen atoms, which each carry a formal charge of −1, together accounting for the ...

Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)
Most compounds considered to be Lewis acids require an activation step prior to formation of the adduct with the Lewis base. Complex compounds such as Et 3 Al 2 Cl 3 and AlCl 3 are treated as trigonal planar Lewis acids but exist as aggregates and polymers that must be degraded by the Lewis base. [10] A simpler case is the formation of adducts ...
The SO molecule has a triplet ground state similar to O 2 and S 2, that is, each molecule has two unpaired electrons. [2] The S−O bond length of 148.1 pm is similar to that found in lower sulfur oxides (e.g. S 8 O, S−O = 148 pm) but is longer than the S−O bond in gaseous S 2 O (146 pm), SO 2 (143.1 pm) and SO 3 (142 pm).
