i have it as nonpolar cuz the Cl are on all sides and they're da same (like PH3)
The bond in boron trichloride, BCl3, is polar covalent.
I don't think BCl4 is even a POSSIBLE molecule since boron has only three valence electrons; perhaps you mean BCl3 (which is nonpolar)?
there is only one answer for BCl3 and that is trigonal planer
Formula: BCl3
