Question

for complete oxidation 1 mole of an organic compound requires 3 mol of oxygen gas what would be the formula of compound?

Answer 1

a⁴O²

Explanation:

Let the molecule of the organic compound be 'a'.

Given,

• 1a+3O₂⇒?

By back calculating,

a+3O₂

a²O¹

But the molecular formula of Oxygen is 2-,

Multiply both of them by 2,

a²⁽²⁾O²⁽¹⁾

a⁴O².
