Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for 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).
Esters of propanoic acid are produced commercially by this method: H 2 C=CH 2 + ROH + CO → CH 3 CH 2 CO 2 R. A preparation of methyl propionate is one illustrative example. H 2 C=CH 2 + CO + CH 3 OH → CH 3 CH 2 CO 2 CH 3. The carbonylation of methanol yields methyl formate, which is the main commercial source of formic acid. The reaction is ...
In organic chemistry, an ortho ester is a functional group containing three alkoxy groups attached to one carbon atom, i.e. with the general formula RC(OR') 3. Orthoesters may be considered as products of exhaustive alkylation of unstable orthocarboxylic acids and it is from these that the name 'ortho ester' is derived.
Ester hydrolysis is an organic reaction which hydrolyzes an ester to a carboxylic acid or carboxylate, and an alcohol. It can be performed with acid as catalyst, or ...
Acetyl chloride is a reagent for the preparation of esters and amides of acetic acid, used in the derivatization of alcohols and amines. One class of acetylation reactions are esterification, for example the reaction with ethanol to produce ethyl acetate and hydrogen chloride: CH 3 COCl + HO−CH 2 −CH 3 → CH 3 −COO−CH 2 −CH 3 + HCl
In organic chemistry and biochemistry esters are the functional group (R'-COOR") consisting of an organic radical united with the residue of any oxygen acid, either organic or inorganic. An ester is a product of the reaction of an acid (usually organic) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R").
In organic chemistry, a nitrate ester is an organic functional group with the formula R−ONO 2, where R stands for any organyl group. They are the esters of nitric acid and alcohols . A well-known example is nitroglycerin , which is not a nitro compound, despite its name.
