explain why the boiling points of alcohols and phenols are much higher than those of alkanes, ethers, etc., of similar molecular mass. discuss the factors that are believed to determine the acidity of alcohols and phenols. list a given series of alcohols or phenols in order of increasing or decreasing acidity.
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 .

Acetic anhydride dissolves in water to approximately 2.6% by weight. Aqueous solutions have limited stability because, like most acid anhydrides, acetic anhydride hydrolyses to give acetic acid: [6] (CH 3 CO) 2 O + H 2 O → 2 CH 3 CO 2 H
