(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.

Benzene is the simplest aromatic compound with C6H6 molecular formula and contains three pi bonds arranged in alternate manner in hexagonal ring. The carbon-carbon bond length in benzene is intermediate to C-C single bond (154 pm) and C = C double bond (134 pm) that is 139 pm due to resonance in molecule.ince six pi electrons are delocalized over whole ring, therefore the cyclically conjugated double bonds represents by a circle and the carbon-carbon bond length becomes equal. This structure of benzene is called as resonance hybrid of benzene and generally used to represents the benzenemolecule.
