Summary

Boron Trifluoride (BF₃) is a colorless, toxic, highly reactive gas. As a strong Lewis acid, it is a key catalyst in organic synthesis, polymerization, and petrochemical processing. It reacts with moisture to form HF, requiring strict anhydrous handling. Its ability to form stable complexes with ethers, amines, and alcohols broadens its industrial and lab applications.
