acetic anhydride structural formula
What is the structural formula of an acid anhydride?
Acid anhydrides contain two acyl groups and have the general formula RC(=O)OC(=O)R or acyl—O—acyl.
The acyl groups may be the same (symmetric) or different (asymmetric or mixed).
The simplest and most common acid anhydrides are symmetrical derivatives of monobasic acids.An acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom.
A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O))2O.
