Step 1: Understand that propane is a type of hydrocarbon, which means it is made up of hydrogen and carbon atoms.
Step 2: Know that the chemical formula for propane is C3H8. This means it has 3 carbon (C) atoms and 8 hydrogen (H) atoms.
Step 3: Visualize the structure: The three carbon atoms are connected in a chain.
Step 4: Each carbon atom can bond with hydrogen atoms. The first and last carbon atoms will bond with 3 hydrogen atoms each, and the middle carbon will bond with 2 hydrogen atoms.
Step 5: Draw the structural formula: Start with three carbon atoms in a line, and add the appropriate number of hydrogen atoms around them.
