Neither! it is a covalent network bond.
nonpolar
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)?
No. The individual bonds are polar, but BF3 is trigonal planar so the overall molecule is not polar.
nonpolar because the equal angles in the trigonal plane cancel out the polarities between iodine and boron

No, boron nitride is often used as an insulator in the semi-conductor industry.
No.
nonpolar or polar
NASA used Boron Nitride in many different ways. It was used as a catalyst when starting Saturn rocket engines. Boron Nitride is also used in one form to protect the outside of the spacecraft. Boron Nitride is one of the hardest chemicals known to man.
boronnitride is BN3
