2 H. [1] The PubChem links give access to more information on the compounds, including other names, IDs, toxicity and safety. [citation needed] Acids from the two-carbon oxalic acid to the ten-member sebacic acid may be remembered using the mnemonic 'Oh My Son, Go And Pray Softly And Silently', and also 'Oh my! Such great Apple Pie, sweet as ...
Kʼahkʼ Pulaj Chan Chaahk, also known as Lord Chac before the decipherment of his corresponding name glyphs, is currently the only archaeologically identified ruler of the pre-Columbian Maya polity at Uxmal, who ruled in the early 10th century. Only a handful of details are known from this king, as hieroglyphic inscriptions, while very ...
In organic chemistry, phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2 and structure HO(O)C−C 6 H 4 −C(O)OH.Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale.

Chac: Dios de la lluvia, also released as Chac: the Rain God and simply Chac, is a 1975 film written and directed by Rolando Klein. The film involves modern Maya peoples invoking the traditional rain deity Chaac. The film is in the Maya languages.
General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
R−CH(Cl)CO 2 H + H 2 O → R−CH(OH)CO 2 H + HCl. Another synthetic pathway for α-hydroxy acids involves the addition of hydrogen cyanide to ketones or aldehydes, followed by the acidic hydrolysis of the cyanohydrin intermediate. [14] R−CHO + HCN → R−CH(OH)CN R−CH(OH)CN + 2H 2 O → R−CH(OH)CO 2 H + NH 3
Lactones are usually named according to the precursor acid molecule (aceto = 2 carbon atoms, propio = 3, butyro = 4, valero = 5, capro = 6, etc.), with a -lactone suffix and a Greek letter prefix that specifies the number of carbon atoms in the heterocycle — that is, the distance between the relevant -OH and the -COOH groups along said backbone.
Terephthalic acid is an organic compound with formula C 6 H 4 (CO 2 H) 2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually. [8] The common name is derived from the turpentine-producing tree Pistacia terebinthus ...
