Trigonal Planar
Boron Triflouride
Yes, BCI3 (boron trichloride) is a covalent compound. It is formed through the sharing of electrons between boron and chlorine atoms, rather than the transfer of electrons that occurs in ionic bonds.
BCl3 is a polar molecule because it has a trigonal planar molecular geometry with one lone pair on the central boron atom. The differences in electronegativity between boron and chlorine atoms create a net dipole moment, making the molecule polar.
