Step 1: Identify the longest carbon chain in the compound. The longest chain has four carbon atoms, which is called butane.
Step 2: Determine the functional groups present. The compound has a carboxylic acid group (-COOH) and a hydroxyl group (-OH).
Step 3: Number the carbon chain starting from the end closest to the carboxylic acid group. This gives the carboxylic acid the lowest possible number.
Step 4: Identify the position of the hydroxyl group. It is on the second carbon of the chain.
Step 5: Combine the information to name the compound. The name includes the position of the hydroxyl group and the base name of the acid, resulting in 2-Hydroxybutanoic acid.
