`NF_(3) " and " NH_(3)` are both pyramidal but differ widely in dipole moment values. Assigne reason.

Even though both NH_(3) " and " NF_(3) are pyramidal, NH_(3) has a higher dipolemoment compared to NF_(3) . Why ?

NH_(3) and NF_(3) are both pyramidal. What observations are made on the difference in bond angles, bond polarities and dipolemoments?

Out of NH_(3) and NF_(3) which is more polar. Explain with the help of dipole moment.

Out of NH_(3) and NF_(3) which is more polar. Explain with the help of dipole moment.

Explain why : Both BF_3 and NH_3 are the molecules of the type AB_3 but their dipole moments are not equal.

Both NF_(3) and NH_(3) possess tetrahedral geometries but the dipole moment of NF_(3) ( 0.23 De bye ) is very low compared with 1.47 D for NH_(3) .This is because

BF_(1) and NF_(3) both molecules, are covalent, but BF_(3) is non - polar and NF_(3) pole. Its reason is
