What type of bond is BF3?
covalent bond BF3 is a molecule consisting of an sp2 hybrid of Boron covalently bonded with 3 atoms of fluorine. The covalent bond tells us that electrons are shared, rather than lost by boron and gained by fluorine. This bond is formed because of Boron's high ionization energy.
Is BF3 planar or nonplanar?
Explanation: Boron has only 3 valence electrons, so when it bonds with F there will only be 3 electron pairs around the boron atom.
