Question

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

Answer 1

The molecular formula may be CHO...

Answer 2

Explanation :

Empirical formula : It is defined as the formula in which the atoms in a molecule is present in their lowest ratio.

Molecular formula : It is defined as the formula in which the atoms in a molecule is present in fixed ratio.

Formula used :

$\frac{\text{ Molecular formula}}{\text{ Empirical formula}}=n$

$\text{ Molecular formula}=\text{ Empirical formula}\times n$

where, 'n' is whole number multiple i.e, 1, 2, 3, 4, so on.

If n = 1 , the molecular formula is $CH_2O_2$

If n = 2 , the molecular formula is $C_2H_4O_4$

If n = 3 , the molecular formula is $C_3H_6O_6$

And so on.
