Boron trifluoride, with the chemical formula BF3, is an inorganic boron compound consisting of boron bound to three fluorine atoms in a trigonal planar molecular geometry. Here are some key properties of this colorless gas:
At standard temperature and pressure, BF3 is a non-flammable diatomic gas. It condenses to a liquid at -100°C and freezes at -127°C. The B-F bonds are very strong, making BF3 stable and resistant to decomposition below 500°C. However, BF3 readily forms adducts and complexes with compounds containing lone electron pairs like ammonia.
BF3 has a piercing, pungent odor and is highly toxic if inhaled. It is generally not reactive with organic compounds except at high temperatures when it can cause fluorination. Upon contact with water, it hydrolyzes to form hydrofluoric acid. Overall, BF3 is a useful Lewis acid and fluorinating agent when handled properly.
