Boron trifluoride ( 3 BF ) accepts lone pair of electrons to form a bond with vacant p orbital. Hence, it is a lewis acid. It is an electron-deficient compound, so it forms dimer to get a stable structure. And It is a covalent com- pound as the electronegative difference of boron and fluorine is less than 1.7.
