(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.

Carbon atoms using sp2 hybrid orbitals. When carbon atoms make use of sp2 hybrid orbitals for sigma bonding, the three bonds lie on the same plane. One such compund is ethene, in which, both carbon atoms make use of sp2 hybrid orbitals. One of the remaining p orbital for each carbon overlap to form a pi bond.
