Q: What is the IUPAC name for the compound with the formula C4H8O2 that has a double bond and a carboxylic acid group?
Solution: The compound has a double bond and a carboxylic acid group, making it Butenoic acid.
Steps: 7
Step 1: Identify the molecular formula C4H8O2. This means the compound has 4 carbon atoms, 8 hydrogen atoms, and 2 oxygen atoms.
Step 2: Recognize that the compound has a carboxylic acid group (-COOH), which is a functional group that indicates the compound is an acid.
Step 3: Note that the compound also has a double bond, which means there is a carbon-carbon double bond (C=C) in the structure.
Step 4: Determine the longest carbon chain that includes the carboxylic acid group and the double bond. In this case, the longest chain has 4 carbon atoms.
Step 5: Since the longest chain has 4 carbons and includes a double bond, it is called 'butene'.
Step 6: Combine the name of the longest chain (butene) with the fact that it is a carboxylic acid. The name becomes 'butenoic acid'.
Step 7: Conclude that the IUPAC name for the compound C4H8O2 with a double bond and a carboxylic acid group is Butenoic acid.
