Final answer:
Upon applying the general molecular formula for alkanes, CnH2n+2, to the given options, each of them follows the pattern expected of an alkane. Therefore, all listed options could indeed be molecular formulas for alkane molecules, making the provided question's intent unclear since there's no incorrect option presented in the context of alkane molecular formulas.
Step-by-step explanation:
Identifying the Incorrect Alkane Molecular Formula
Alkanes are a class of hydrocarbons that follow the general molecular formula CnH2n+2. This formula helps us determine the number of hydrogen atoms in an alkane based on the number of carbon atoms present. If we apply this formula to the provided options:
Given that all options follow the general formula for alkanes, none of these options could be incorrectly identified as an alkane by their molecular formula alone.
