Solution

The correct option is D Statement-1 is true, Statement-2 is false
Statement-1 : Carbon and hydrogen elements are estimated by Liebig's method.
A known mass of an organic compound is heated in the presence of pure oxygen. The carbon dioxide and water formed are collected and weighed. The percentages of carbon and hydrogen in the compound are calculated from the masses of carbon dioxide and water.
Statement-2 : All the organic compounds contain C as essential constitute.
Hence, Statement-1 is True, Statement-2 is False.
