Question

The empirical formula of a compound is CH2O2. What could be its molecular formula? (A) C2H2O2 (B) C2H2O4 (C) C2H4O4 (D) CH4O4

Since empirical formula is multiplied by n to get molecular formula. CH2O2 will give only C2H4O4 as its molecular formula. (CH2O2)n where n = 1,2,3,... etc.

Q. The empirical formula of a compound is $C H_{2} O_{2}$ . What could be its molecular formula?

$C_{2} H_{2} O_{2}$

$C_{2} H_{2} O_{4}$

$C_{2} H_{4} O_{4}$

$C H_{4} O_{4}$

Since empirical formula is multiplied by $n$ to get molecular formula.
$C H_{2} O_{2}$ will give only $C_{2} H_{4} O_{4}$ as its molecular formula.
$(C H_{2} O_{2})_{n}$ where $n = 1, 2, 3, ...$ etc.
