The empirical formula of an acid is CH₂O₂ , the probable molecular formula of acid may be

Options

(a) CH₂O
(b) CH₂O₂
(c) C₂H₄O₂
(d) C₃H₆O₄

Correct Answer:

CH₂O₂

Explanation:

The molecular formula of the acid = (empirical formula)(n).
Where ‘n’ is an integer. Therefore the molecular formula = CH₂O₂ , here n = 1 . The other molecular formula do not fit the above equation.
