[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.
2-Hexanol (hexan-2-ol) is a six-carbon alcohol in which the hydroxy group (OH) is located on the second carbon atom. Its chemical formula is C 6 H 14 O or C 6 H 13 OH. It is an isomer of the other hexanols. 2-Hexanol has a chiral center and can be resolved into two different enantiomers. Its toxicity is based on metabolism to hexane-2,5-dione. [3]
For sulfuric acid, computational analysis (with natural bond orbitals) confirms a clear positive charge on sulfur (theoretically +2.45) and a low 3d occupancy. Therefore, the representation with four single bonds is the optimal Lewis structure rather than the one with two double bonds (thus the Lewis model, not the Pauling model). [6]
Vanadium(II) sulfate describes a family of inorganic compounds with the formula VSO 4 (H 2 O) x where 0 ≤ x ≤ 7. The hexahydrate is most commonly encountered. It is a violet solid that dissolves in water to give air-sensitive solutions of the aquo complex. The salt is isomorphous with [Mg(H 2 O) 6]SO 4.

Clar's rule states that for a benzenoid polycyclic aromatic hydrocarbon (i.e. one with only hexagonal rings), the resonance structure with the largest number of disjoint aromatic π-sextets is the most important to characterize its chemical and physical properties. Such a resonance structure is called a Clar structure. In other words, a ...
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.
2,5-Hexanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 CH(OH)CH 3. It is both a glycol and a secondary alcohol. [1] It is a colorless water-soluble viscous liquid. [2] [3] [4] The chemical properties are well understood and have been extensively reported and studied. [5]
