Q: What is the IUPAC name for the compound with the formula C4H8O2 that has a double bond and a carboxylic acid functional group?

Solution: The compound is 2-Butenoic acid, as it has a double bond and a carboxylic acid functional group.

Steps: 6

Step 1: Identify the molecular formula C4H8O2. This indicates the compound has 4 carbon atoms, 8 hydrogen atoms, and 2 oxygen atoms.
Step 2: Recognize that the compound has a carboxylic acid functional group, which is represented as -COOH.
Step 3: Determine that the presence of a double bond means there is a carbon-carbon double bond (C=C) in the structure.
Step 4: Count the carbon atoms in the longest chain that includes the carboxylic acid group. The longest chain with 4 carbons is called butanoic acid.
Step 5: Since there is a double bond, we need to specify its position. The double bond is between the second and third carbon atoms, making it 2-butenoic acid.
Step 6: Combine the information: the compound is a butenoic acid with a double bond at the second carbon, leading to the final IUPAC name: 2-Butenoic acid.
