D
Verified step by step guidance1
Identify the molecular formula of propane, which is C3H8. This indicates that the molecule contains three carbon atoms and eight hydrogen atoms.
Recall that carbon atoms form four covalent bonds. This is a key point in determining how the atoms are connected in the structure.
Arrange the three carbon atoms in a linear chain. This is because propane is an alkane, which typically has a straight or branched chain of carbon atoms.
Attach hydrogen atoms to each carbon atom to satisfy the tetravalency of carbon. Each carbon should have a total of four bonds, including bonds with other carbon atoms and hydrogen atoms.
Ensure that the total number of hydrogen atoms is eight, as indicated by the molecular formula. Adjust the placement of hydrogen atoms if necessary to achieve this count.
