Laissaigne’s extract is made to:a)Convert ionic compounds to covalent ...
Laissaigne's extract is a chemical method used to convert covalent compounds to ionic compounds. It is specifically used to detect the presence of nitrogen, sulfur, and halogens in organic compounds.
- Laissaigne's extract is a mixture of sodium metal and carbon. When this extract is heated with an organic compound containing nitrogen, sulfur, or halogens, it undergoes a series of reactions that result in the formation of ionic compounds.
- The first step involves the reaction between sodium metal and the organic compound. Sodium reacts with nitrogen, sulfur, or halogens to form sodium nitride, sodium sulfide, or sodium halide, respectively. These compounds are ionic in nature.
- The second step involves the dissolution of the ionic compounds in water. This step is necessary to separate the ionic compounds from the organic compound.
- The final step involves the detection of the dissolved ionic compounds. Various tests can be performed on the solution to identify the presence of nitrogen, sulfur, or halogens. For example, the presence of nitrogen can be detected by adding sodium hypochlorite solution and observing the formation of a blue precipitate of Prussian blue.
- In summary, Laissaigne's extract converts the covalent compounds containing nitrogen, sulfur, or halogens into their corresponding ionic compounds, which are then dissolved in water for further analysis.
Therefore, option C, which states that Laissaigne's extract is used to convert covalent compounds to ionic compounds, is the correct answer.
