key term - Skeletal structure

Definition

In organic chemistry, a skeletal structure is a simplified representation of a molecule that shows the arrangement of atoms and bonds but omits hydrogen atoms attached to carbon. This depiction focuses on the carbon skeleton and heteroatoms (non-carbon atoms), making it easier to visualize complex molecules.
