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`.

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

The formation of chemical compounds takes place as a result of combination of atoms of various elements. Explain how ionization enthalpy (I.E) and electron gain enthalpy (E.G.E) determine whether atoms of elements will combine to form ionic compounds.

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

The dipole moments of polyatomic molecules not only depends upon bond dipoles but also on the spatial arrangement of various bonds in the molecule. Compare dipole moments of NH_3 and NF_3 .

Compare the dipole moments of the compounds in each fo the following sets. BF_3 and BCl_3

Dipole moment is used to predict the shape of molecules. b) Which is having high dipole moment ? NH_3 or NF_3 ? Why?

Which of the following is untrue regarding BF_3 ? It is a Lewis acid , It is a planar molecule, It has a dipole moment, It forms a compound with NH_3

When bromo benzene is monochlorinated, two Isomeric compounds A and B are obtained. Monobromination of A gives several isomeric products of molecular formula C_6 H_3 CI Br_2 , while monobromination of B yields only 2 isomers C and D . Compound C is identical with one of the compounds obtained from bromination of A , however D is totally different from any of the isomeric cómpounds obtained from the bromination of A , Give structures of A, B, C and D and also structures of four isomeric monobrominated products of A Support your answer with reasoning.

Select the molecule or ion having larger property mentioned in each of the following pairs: a) NF3, NH3 ;dipole moment b) NH3, PH3 ;bond angle c) CO2, BF3 ;bond angle.
