(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.

Best Answer: CCl4 is a tetrahedral molecule comprising four single bonds, known as sigma bonds, between the carbon atom and the chlorine atoms. In this type of bonding the 2s orbital and the three 2p orbitals of the carbon atom are mixed to produce four identical orbitals, a process known as sp3 hybridization.
