1.	IUPAC name of is :-(1) Acetic anhydride(2) Methanoic anhydride(3) Ethanoic methanoic anhydride(4) Ethanoic anhydride
Answer» EXPLANATION: An acyclic carboxylic anhydride derived from acetic acid. Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O. Commonly ABBREVIATED Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely USED as a reagent in organic synthesis. Formic anhydride[1] Anhydride is a chemical compound where two carbonyl group is attached by one oxygen. Generally it is OBTAINED by the reaction of two organic acid end up with the elimination of water. Similarly Ethanoic methanoic anhydride is formed by the reaction of ethanoic acid and methanoic acid. Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH₃CO)₂O. Commonly abbreviated Ac₂O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
