(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

It actually bonds. It will hold more than 8 electrons. Xenon having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. XeF4 is d2sp3 hybridized and contains 2 lone pair and 4 bonding pairs of valence electrons around the Xenon.t actually bonds. It will hold more than 8 electrons.
