Hint: The naming of the organic compounds is based on the functional group and number of carbon atoms in the chain. In the compound, the main functional group is acid anhydride and for the naming of the acid anhydride, we have to count the number of carbon atoms on either side of the central oxygen atom.

Complete answer:
IUPAC whose full form is the International Union of Pure and Applied Chemistry is a system that names the chemical compound and it is accepted globally. The naming of the organic compounds is based on the functional group and the number of carbon atoms in the chain.
So, the given compound in the question is:

This is in the condensed form, so by writing the expansion of the given compound.

So, the main and only functional group in the above compound is the anhydride group which is written as:

So, when the acid anhydrides are named then in the suffix part we use the anhydride word.
Now, we have to count the number of carbon atoms on either side of the central oxygen atom of the anhydride group. On one side there are two carbon atoms and on the other side, there is one carbon atom. For one carbon atom, we use meth and for two carbon atoms, we use eth.
So, the name of the given compound will be Ethanoic methanoic anhydride.

Note:
The given compound can also be named as Acetic formic anhydride and in the IUPAC naming ethanoic is written first then the methanoic is written because alphabetically e comes before m.
