The empirical formula of an acid is `CH_(2)O_(2)`, the probable molecular formula of the acid may be

Options

A. `C_2H_4O_2`
B. `C_3H_6O_4`
C. `C_2H_2O_4`
D. `CH_2O_2`

Answer

D

Explanation

Empirical formula of acid `=CH_2O_2`
We know that molecular formula = n(empirical formula)
If n = 1, molecular formula=`(CH_2O_2)_(1) =CH_2O_2`
If n = 2, molecular formula `=(CH_2O_2)_2=C_2H_4O_4`
If n = 3, molecular formula = `(CH_2O_2)_3=C_3H_5O_6`
Thus, the probable molecular formula `=CH_2O_2`
