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: Learn about aldehydes. Aldehydes are a type of organic compound that have a specific structure.
Step 3: Identify the key feature of aldehydes. Aldehydes contain a carbonyl group, which is a carbon atom double-bonded to an oxygen atom.
Step 4: Note the position of the carbonyl group in aldehydes. In aldehydes, the carbonyl group is always located at the end of the carbon chain.
Step 5: Write the structure of the carbonyl group in aldehydes. The carbonyl group in aldehydes is represented as -CHO.
