  2. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...

  3. Bent molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Bent_molecular_geometry

    Nonlinear geometry is commonly observed for other triatomic molecules and ions containing only main group elements, prominent examples being nitrogen dioxide (NO 2), sulfur dichloride (SCl 2), and methylene (CH 2). This geometry is almost always consistent with VSEPR theory, which usually explains non-collinearity of atoms with a presence of ...

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.

    en.wikipedia.org/wiki/VSEPR_theory

    In effect, they considered nitrogen dioxide as an AX 2 E 0.5 molecule, with a geometry intermediate between NO + 2 and NO − 2. Similarly, chlorine dioxide (ClO 2) is an AX 2 E 1.5 molecule, with a geometry intermediate between ClO + 2 and ClO − 2. [citation needed] Finally, the methyl radical (CH 3) is predicted to be trigonal pyramidal ...

  7. Metal sulfur dioxide complex - Wikipedia

    en.wikipedia.org/wiki/Metal_sulfur_dioxide_complex

    The "insertion" proceed the sulfur dioxide between the metal and the alkyl ligand leads to the O, O'-sulphinate. Alternatively an O-sulphinate can arise. Both of these intermediates commonly convert to an S-sulphinate. [5] S-sulphinate has sulfur–oxygen stretching frequencies from 1250–1000 cm −1 and 1100–1000 cm −1.

  8. Trigonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_planar_molecular...

    In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1] In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°.

  9. Linear molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Linear_molecular_geometry

    The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°. Linear organic molecules , such as acetylene ( HC≡CH ), are often described by invoking sp orbital hybridization for their carbon centers.
