Step 1: Understand what a functional group is. A functional group is a specific group of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.
Step 2: Identify the type of compound we are discussing. In this case, we are talking about ketones.
Step 3: Learn about the carbonyl group. The carbonyl group is a functional group that consists of a carbon atom double-bonded to an oxygen atom (C=O).
Step 4: Recognize the structure of ketones. In ketones, the carbonyl group (C=O) is located between two carbon atoms.
Step 5: Write the functional group of ketones. The functional group of ketones is represented as -CO-, indicating the carbonyl group is between two carbon atoms.
