WebAnd we can form those from carboxylic acids. So if we start with the carboxylic acid, and our first step, add a base, like sodium hydroxide, and our second step, add an acyl chloride, then we'd form our acid anhydride as our product. Now if you think about a mechanism, sodium hydroxide's a base.

Web1 – Simple forms of dicarboxylic acids. Short-chain dicarboxylic acids are of great importance in the general metabolism and up to n=3 they cannot be considered as lipids since their water solubility is important. The simplest of these intermediates is oxalic acid (n=0), the others are malonic (n=1), succinic (n=2) and glutaric (n=3) acids. Web1 Answer. The p K a of the C H X 2 group in a dicarbonyl compound is roughly 10, whereas the p K a of a carboxylic acid is roughly 5. For example, dimethyl malonate has a p K a of 13 whereas acetic acid has a p K a of 4.7. So, the C–H bond acidity is not likely to be under consideration in any of your compounds.
