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 ′).

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).
A general acyl group (blue) in a ketone (top left), as an acylium cation (top centre), as an acyl radical (top right), an aldehyde (bottom left), ester (bottom centre) or amide (bottom right). ( R 1 , R 2 and R 3 stands for organyl substituent or hydrogen in the case of R 1 )
General Description Acetic acid: an organic acid; is one of the simplest carboxylic acids: Acetone: an organic compound; simplest example of the ketones: Acetylene: a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block Ammonia: inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer
IUPAC states "The esters are often called urethanes or urethans, a usage that is strictly correct only for the ethyl esters." [44] But also states, "An alternative term for the compounds R2NC(=O)OR' (R' not = H), esters of carbamic acids, R,NC(=O)OH, in strict use limited to the ethyl esters, but widely used in the general sense". [45]
[1] [3] The general formula for such an acyl halide can be written RCOX, where R may be, for example, an alkyl group, CO is the carbonyl group, and X represents the halide, such as chloride. Acyl chlorides are the most commonly encountered acyl halides, but acetyl iodide is the one produced (transiently) on the largest scale.
The general formula of orthoesters. 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 ...
Ethyl lactate, also known as lactic acid ethyl ester, is the organic compound with the formula CH 3 CH(OH)CO 2 CH 2 CH 3. It is the ethyl ester of lactic acid. A colorless liquid, it is a chiral ester. Being naturally derived, it is readily available as a single enantiomer. It is commonly used as a solvent. [4]
