Concept Introduction:
Line structure: Line structure is a simplest representation of a hydrocarbon. In line structure, the chain of carbon atoms is shown as a zigzag line. The end of each short line in the zigzag represents a carbon atom. Since the carbon nearly always has a valence of four in organic compounds, it is not necessary to show the hydrogen atoms.
