The empirical formula (CH) represents the simplest whole number ratio of atoms in this compound, and it's also the molecular formula since there's only one carbon (C and one hydrogen (H) in the molecule.

To determine which molecular formula is correctly paired with its empirical formula, you need to understand the concept of empirical and molecular formulas. The empirical formula represents the simplest whole number ratio of atoms in acompound. The molecular formula represents the actual number of atoms of each element in a molecule

This pair is incorrect. The empirical formula for benzene (C₆H₆) is CH because it represents the simplest whole number ratio of atoms. However, the molecular formula for benzene is also C₆H₆, not just CH.

This pair is incorrect for the same reason as in option B. The empirical formula for benzene is CH, but the molecular formula is also C₆H₆.

This pair is incorrect. The empirical formula (CH) represents the simplest whole number ratio of atoms in this compound, but the molecular formula should have a 2 after H (CH₂) to represent that there are two hydrogen atoms for every carbon atom in the molecule.

This is incorrect.
