Question

The empirical formula of an acid is $CH_{2}O_{2}$, the probable molecular formula of acid may be

• A. $CH_{2}O$
• B. $CH_{2}O_{2}$
• C. $C_{2}H_{4}O_{2}$
• D. $C_{3}H_{6}O_{4}$

Answer 1

Answer: (B)

$CH_{2}O_{2}$

Answer 2

Empirical formula of an acid is $CH_{2}O_{2}$

$(\text{Empirical formula})_{n} =$Molecular formula

n = whole no. multiple i.e. 1,2,3,4..............

If $n = 1$molecular formula $CH_{2}O_{2}$.
