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.

corundum (Al 2 O 3) aluminium oxide hydroxides diaspore (α-AlO(OH)) boehmite or böhmite (γ-AlO(OH)) akdalaite (5Al 2 O 3 ·H 2 O) (once believed to be 4Al 2 O 3 ·H 2 O), also called tohdite; aluminium hydroxides. gibbsite (often designated as γ-Al(OH) 3, but sometimes as α-Al(OH) 3, [4] sometimes called hydrargillite or hydrargyllite)
7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa, commonly known as kratom. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
[2] [3] In aqueous solution, it exists as a mixture of at least four species, which rapidly interconvert. [4] Structures and distribution of glycolaldehyde as a 20% solution in water. Notice that the free aldehyde is a minor component. In acidic or basic solution, the compound undergoes reversible tautomerization to form 1,2-dihydroxyethene. [5]
The 1 H NMR spectrum of arsenous acid solutions consists of a single signal consistent with the molecule's high symmetry. [3] In contrast, the nominally related phosphorous acid H 3 PO 3 adopts the structure HPO(OH) 2. The structural analogue of arsenous acid (P(OH) 3) is a very minor equilibrium component of such solutions. The differing ...
When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...

Vanadium(III) fluoride is the chemical compound with the formula V F 3. This yellow-green, refractory solid is obtained in a two-step procedure from V 2 O 3 . [ 4 ] Similar to other transition-metal fluorides (such as MnF 2 ), it exhibits magnetic ordering at low temperatures (e.g. V 2 F 6 .4H 2 O orders below 12 K [ 5 ] ).
