A 'carbocyclic' compound is an organic molecule where the ring structure is composed entirely of carbon atoms. Think of it like building a fort out of LEGO bricks, but instead of LEGOs, you're using carbon atoms to create a closed shape. These rings can have different sizes and can have single or multiple bonds between the carbon atoms. Unlike heterocyclic compounds, carbocyclic rings don't contain any other elements like nitrogen or oxygen within the ring. It's carbon all the way! They form the backbone of many important organic molecules.
