Let the organic compound X is = CxHyOz
Here moles of C = x, moles of H = y, moles of O = z
Given, WHWC = 14
∴ yx = 1WH 12WC = 14 × 121 = 31
Also Given, WOWC = 43
∴ zx = 16WO 12WC = 43 × 1216 = 1
⇒ x = z
∴ Empirical formula = CxH3xOx = CH3O
As compound is saturated acyclic organic
compound, so molecular formula = C2H6O2
C2H6O2 + 25 O2 → 2CO2 + 3H2O
For 1 mole of C2H6O2 number of moles of O2 required = 25
∴ For 2 mole of C2H6O2 number of moles
of O2 required = 25 × 2 = 5
