JEE Main 2025 Chemistry question
On complete combustion 1.0g of an organic compound (X) gave 1.46 g of CO₂ and 0.567 g of H₂O. The empirical formula mass of compound (X) is g. (Given molar mass in g mol⁻¹ C : 12, H : 1, O : 16)
Answer: (1)
Solution
%C=39.8, %H=6.3, %O=53.9. Empirical formula = CH2O, mass = 30 g/mol.
