Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

The hydrated tetraborate anion occurs in the mineral borax (sodium tetraborate octahydrate) with the formula Na 2 [B 4 O 5 (OH) 4]·8H 2 O. The borax chemical formula is also commonly written in a more compact notation as Na 2 B 4 O 7 ·10H 2 O. Sodium borate can be obtained in high purity and so can be used to make a standard solution in ...
Tetrahydroxyborate is an inorganic anion with the chemical formula [BH 4 O 4] − or [B(OH) 4] −. It contributes no colour to tetrahydroxyborate salts. It is found in the mineral hexahydroborite, Ca(B(OH) 4) 2 · 2 H 2 O, originally formulated CaB 2 O 4 · 6 H 2 O. [2] It is one of the boron oxoanions, and acts as a weak base.
For simple molecules, a condensed (or semi-structural) formula is a type of chemical formula that may fully imply a correct structural formula. For example, ethanol may be represented by the condensed chemical formula CH 3 CH 2 OH, and dimethyl ether by the condensed formula CH 3 OCH 3.
It consists of a methylene bridge (−CH 2 − unit) bonded to a hydroxyl group (−OH). This makes the hydroxymethyl group an alcohol. It has the identical chemical formula with the methoxy group (−O−CH 3) that differs only in the attachment site and orientation to the rest of the molecule. However, their chemical properties are different ...

Orthocarbonic acid, carbon hydroxide, methanetetrol is the name given to a hypothetical compound with the chemical formula H 4 CO 4 or C(OH) 4. Its molecular structure consists of a single carbon atom bonded to four hydroxyl groups. It would be therefore a fourfold alcohol.
