The empirical formula for a compound is CH sub 2 If n is a whole number, which shows a correct relationship between the molecular formula and the empirical formula?

A molecular formula is a whole-number multiple of the empirical formula. If the multiplier is n, CH₂ becomes CₙH₂ₙ, so the carbon subscript in the molecular formula is n times the carbon subscript in the empirical formula. Therefore, the correct relationship is that in choice C.
