In organic chemistry, 3-hydroxybutanal (acetaldol, aldol) is an organic compound with the formula CH 3 CH(OH)CH 2 CHO and the structure H 3 C−CH−CH 2 −CH=O. It is classified as an aldol (R−CH(OH)−CHR'−C(=O)−R") and the word "aldol" can refer specifically to 3-hydroxybutanal. It is formally the product of the dimerization of ...

In solution, it can ionize by a loss of a proton to produce the lactate ion CH 3 CH(OH)CO − 2. Compared to acetic acid, its pK a is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group.
The product, CH 3 CH(OCH 2 CH 3) 2, is formally named 1,1-diethoxyethane but is commonly referred to as "acetal". [39] This can cause confusion as "acetal" is more commonly used to describe compounds with the functional groups RCH(OR') 2 or RR'C(OR'') 2 rather than referring to this specific compound — in fact, 1,1-diethoxyethane is also ...
For example, butanol H 3 C−(CH 2) 3 −OH, methyl propyl ether H 3 C−(CH 2) 2 −O−CH 3, and diethyl ether (H 3 CCH 2 −) 2 O have the same molecular formula C 4 H 10 O but are three distinct structural isomers. The concept applies also to polyatomic ions with the same total charge. A classical example is the cyanate ion O=C=N − and ...
ch 3 • + •ch 3 → c 2 h 6 During the period 1847–1849, in an effort to vindicate the radical theory of organic chemistry , Hermann Kolbe and Edward Frankland produced ethane by the reductions of propionitrile ( ethyl cyanide ) [ 7 ] and ethyl iodide [ 8 ] with potassium metal, and, as did Faraday, by the electrolysis of aqueous acetates.
Lactonitrile is the organic compound with the formula CH 3 CH(OH)CN. It is an intermediate in the industrial production of ethyl lactate and lactic acid. [1] [2] [3] It is the cyanohydrin of acetaldehyde. It is a colorless liquid, although degraded samples can appear yellow.
Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.
