Answer 1

The possible molecular formula for C₂H5N is C4H10N.

Step-by-step explanation:

The empirical formula of C₂H5N indicates the simplest ratio of the atoms present in the compound. To determine a possible molecular formula, we need to find the actual number of atoms in the compound. The formula mass is a multiple of the empirical formula mass, meaning the molecular formula will have a higher mass than the empirical formula. To find the molecular formula, we compare the empirical formula mass (29 g/mol) to the formula mass (59 g/mol) and determine the multiplier. The empirical formula mass is half the formula mass, so the multiplier is 2. Therefore, the possible molecular formula for C₂H5N is C4H10N (choice A).
