From Wikipedia, the free encyclopedia. Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.ike most acid anhydrides, the carbonyl carbon of acetic anhydride is a potent electrophile as the leaving group for each carbonyl carbon (a carboxylate) is a good electron-withdrawing group.
These are the strong acids. What makes them 'strong' is that they completely dissociate into their ions (H+ and an anion) when they are mixed with water. Any other acid is a weak acid. There are only seven strong acids, so you might want to commit the list of strong acids to memory. Note some instructors may ask for the 6 strong acids. That typically refers to the first 6 acids on this list.
