Final answer:
Without the correct structural formula of the hydrocarbon, it is impossible to determine its molecular or empirical formulas. Still, the empirical formula represents the simplest whole-number ratio of atoms in a compound, and the molecular formula denotes the actual number of atoms. The correct option is c.
Step-by-step explanation:
The question provided seems to be asking for the molecular formula and empirical formula of a hydrocarbon. The molecular formula represents the actual number of carbon and hydrogen atoms in the hydrocarbon molecule, while the empirical formula is the simplest whole-number ratio of these atoms.
It appears that in the question, due to typographical errors, the structural formula is unclear. Therefore, we cannot give an accurate answer to the specific options presented (C5H10 and CH2, C5H10 and CH, C4H8 and CH2, C4H8 and CH3) regarding the empirical and molecular formulas.
However, we can provide a general approach to finding these formulas. To determine the empirical formula, one would divide the moles of each element by the smallest number of moles to get the simplest ratio.
To verify the molecular formula, one might use the experimentally determined molecular mass along with the empirical formula mass. The correct option is c.
