What is the IUPAC name for the compound with the formula CH₃COOH?

Step 1: Identify the formula CH₃COOH. This formula represents a molecule with a carbon chain and a carboxylic acid group.
Step 2: Recognize that CH₃COOH has two carbon atoms. The 'CH₃' part is a methyl group (1 carbon), and the 'COOH' part indicates a carboxylic acid (1 carbon).
Step 3: Count the total number of carbon atoms. There are 2 carbon atoms in total.
Step 4: Use the IUPAC naming rules for carboxylic acids. The name is based on the number of carbon atoms in the longest chain.
Step 5: Since there are 2 carbon atoms, the prefix 'eth-' is used. The suffix for carboxylic acids is '-oic acid.'
Step 6: Combine the prefix and suffix to get the IUPAC name: ethanoic acid.
Step 7: Note that ethanoic acid is commonly known as acetic acid.
