Which of the following is not a use of fluorine compounds?

Fluorine forms a variety of inorganic compounds that have important industrial, chemical, and biological applications. Understanding the uses of these compounds is a key part of inorganic chemistry.

Antimony trifluoride (SbF₃) is commonly used in chemical synthesis as a fluorinating agent, but it also has applications in certain ceramic processes, including the preparation of specialized glazes. Sodium fluoroacetate (NaCH₂FCOO) is a highly toxic compound used as a rodenticide. Its effectiveness comes from the presence of fluorine, which disrupts metabolic processes in pests.

Copper(II) fluoride (CuF₂) is used in the ceramic industry. It acts as a flux in glazes and helps produce specific colors and textures in ceramic materials. Its chemical stability and reactivity make it suitable for high-temperature applications in industrial ceramics.

All three compounds demonstrate the versatility of fluorine chemistry. Fluorine’s high electronegativity and ability to form strong bonds with metals and nonmetals contribute to the chemical stability, toxicity, and industrial usefulness of these compounds.

This question reinforces the importance of knowing the practical uses of fluorine compounds in both industrial and laboratory contexts. Recognizing the applications of SbF₃, sodium fluoroacetate, and CuF₂ helps students understand trends in inorganic chemistry, including halogen reactivity, compound stability, and industrial relevance. The answer “None of the above” indicates that all listed compounds indeed have real-world applications consistent with their chemical properties.
