Which of the following methods is used to estimate hydrogen in an organic compound?

Correct answer: A. Combustion method

  • A. Combustion method
  • B. Duma's method
  • C. Kjeldahl's method
  • D. All of the above methods are for different purposes

Explanation

The combustion method is a commonly used technique to estimate the percentage of carbon and hydrogen in an organic compound. In this method, the organic compound is burned in the presence of excess oxygen. The combustion products, carbon dioxide (CO2) and water (H2O), are collected and weighed. From the weights of CO2 and H2O, the percentage of carbon and hydrogen in the original compound can be calculated.Therefore, the combustion method is used for estimating both carbon and hydrogen content in an organic compound.In summary, the combustion method (option a) is the correct method for estimating hydrogen in an organic compound, while the other options involve methods for different elements (nitrogen) or serve different purposes.

About Fundamental Concepts of Chemistry

Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
