Define carboxylic acid. carboxylic acid synonyms, carboxylic acid pronunciation, carboxylic acid translation, English dictionary definition of carboxylic acid. n. An organic acid that contains one or more carboxyl groups. American Heritage® Dictionary
Carboxylic acids are small organic acids with one or more carboxylic acid groups. Their properties vary significantly with their carbon-chain length, molecular structure, and the presence of additional functional groups. Figure 1 shows some important carboxylic acids and their chemical structures. These...
Carboxylic acid, any of a class of organic compounds in which a carbon atom is bonded to an oxygen atom by a double bond and to a hydroxyl group by a single bond. They are generally more acidic than other organic compounds containing hydroxyl groups but
Reactions of chromyl chloride with carboxylic acid anhydrides [(RCO)2O where R = CH3 , C2H5 and n-C3H7 ] give dinuclear oxo-bridged complexes of the type, [Cr2O(OOOCR)3 ]Cl. These compounds behave as non-electrolytes in polar organic solvents. IR spectra suggest the presence of ...
