The molecular geometry of `BF_3` is…………

Define dipole moment. The dipole moment of BF_3 is zero. Why?

The dipole moment of BF_3 is zero eventhough the B-F bonds are polar, Justify.

The net dipole moment of a polyatomic molecule depends on the spatial arrangement of various bonds in the molecule. The dipole moment of BF_3 is zero while that of NF_3 is not zero. Justify

The formation of chemical compounds takes place as a result of combination of atoms of various elements. The dipole moment of NH_3 is 0.49 D and that of BF_3 is zero. From the above values predict molecular structure of NH_3 and BF_3 .

BF_3 and NH_3 are tetra atomic molecules. But the shape of BF_3 is different from that of NH_3 . Explain this using hybridisation.

The molecular mass of benzene is 78 and its percentage composition is 92.3 C and 7.69 H. Determine the molecular formula of benzene?

Choose the pair of compounds which have different hybridisation but same molecular geometry ?
