An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
Esters (R−C(=O)O−R') are named as alkyl derivatives of carboxylic acids. The alkyl (R') group is named first. The alkyl (R') group is named first. The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to " -oate " or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 ...
Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite.Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater.
It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.
Formate salts have the formula M(O 2 CH)(H 2 O) x. Such salts are prone to decarboxylation. For example, hydrated nickel formate decarboxylates at about 200 °C with reduction of the Ni 2+ to finely powdered nickel metal: Ni(HCO 2) 2 (H 2 O) 2 → Ni + 2 CO 2 + 2 H 2 O + H 2. Such fine powders are useful as hydrogenation catalysts. [1]
In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion , an ion with negative charge . Carboxylate salts are salts that have the general formula M(RCOO) n , where M is a metal and n is 1, 2,....
