Questions: Draw the expanded, or complete, structural formula for the hydrocarbon represented by the line-angle, or skeletal, structure shown. Draw the complete structural formula. Include all hydrogen atoms.

Solution Steps

Each vertex and endpoint in the line-angle structure represents a carbon atom.

Each carbon atom forms four bonds. Add hydrogen atoms to each carbon atom until it has four bonds.

Draw the complete structural formula, showing all carbon and hydrogen atoms and their bonds.

Final Answer

 CH3
