(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.

A carbonâoxygen bond is a covalent bond between carbon and oxygen.ond lengths of C=O bonds are around 123 pm in carbonyl compounds. The C=O bonds in acyl halides have partial triple bond character and are subsequently very short: 117 pm. Compounds with formal CâO triple bonds do not exist except for carbon monoxide, which has a very short, strong bond (112.8 pm).
