The electronegativity difference between...

The electronegativity difference between N and F is greater than that between N and H yet the dipole moment of `NH_(3)` (1.5 D) is larger than that of `NF_(3)`(0.2D) This is because

A

In `NH_(3)` the atomic dipole and bond dipole are in the opposite directions whereas in `NF_(3)` these are in the same direction

B

In `NH_(3)` as well as in `NF_(3)` the atomic dipole and bond dipole are in the same direction

C

In `NH_(3)` the atomic dipole and bond dipole are in the same direction whereas in `NF_(3)` these are in opposite directions

D

In `NH_(3)` are well as in `NF_(3)` the atomic dipole and bond dipole are in opposite directions

Covalent molecules formed by heteroatoms bound to have some ionic character. The ionic character is due to shifting of the electron pair towards A or B in the molecule AB. Hence, atoms acquire small and equal charge but opposite in sign. Such a bond which has some ionic character is described as polar covalent bond. Polar covalent molecules can exhibit dipole moment. Dipole moment is equal to the product of charge separation, q and the bond length, d for the bond. The unit of dipole moment is Debye. One Debye is equal to 10^(-18) esu cm. Dipole moment is a vector quantity. It has both magnitude and direction. Hence, dipole moment of molecules depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moments help to predict the geometry of the molecules. Dipole moment values can be used to distinguish between cis-and traps-isomers, ortho-, meta-and para-forms of a substance, etc. The percentage of ionic character of a bond can be calculated by the application of the following formula : % " ionic character " = ("Experimental value of dipole moment ")/("Theoretical value of dipole moment ") xx 100 The dipole moment of NF_(3) is very much less than that of NH_(3) because :
