The correct Answer is:
To determine the IUPAC name of the compound `(CH₃CH₂CO)₂O`, we can follow these steps: ### Step 1: Identify the structure of the compound The given formula `(CH₃CH₂CO)₂O` indicates that there are two propanoyl (propanoic acid) groups connected through an oxygen atom. This suggests that the compound is an anhydride. ### Step 2: Draw the structural formula The structural formula can be represented as: ``` O // CH3-CH2-C \ O / CH3-CH2-C ``` This shows that two propanoyl groups are bonded to an oxygen atom. ### Step 3: Determine the type of anhydride Since both sides of the anhydride are identical (both are propanoyl), this is a symmetric anhydride. ### Step 4: Name the anhydride For symmetric anhydrides, the name is derived from the corresponding carboxylic acid. In this case, the carboxylic acid is propanoic acid (from propanoyl). Therefore, the name of the anhydride will be "propanoic anhydride". ### Final Answer The IUPAC name of `(CH₃CH₂CO)₂O` is **propanoic anhydride**. ---
