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

Options

A. `C_(2)H_(4)O_(2)`
B. `C_(3)H_(6)O_(4)`
C. `C_(2)H_(2)O_(4)`
D. `CH_(2)O_(2)`

Answer

D

Explanation

Empirical formula of acid = `CH_(2)O_(2)`
We know that molecular formula = n (empirical formula)
If n = 1, molecular formula = `(CH_(2)O_(2))_(1)=CH_(2)O_(2)`
If n = 2, molecular formula = `(CH_(2)O_(2))_(2)=C_(2)H_(4)O_(4)`
If n = 3, molecular formula = `(CH_(2)O_(2))_(3)=C_(3)H_(6)O_(6)`
Thus, the probable molecular formula = `CH_(2)O_(2)`
