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

Between NF_(3) and BF_(3) , which is the more polar molecule? Why?

Which out of NH_(3) and NF_(3) has higher dipole ment and why ?

Which out of NH_(3) and NF_(3) has higher dipole moment and why?

Out of the following which has highest dipole moment?

All molecules with polar bonds have dipole moment.

Which is more basic and why ? NF_3 or NH_3 .

Assertion (A): In dilute benzene solutions, equimolar addition of R_(3)N and HCI produce a substance with a dipole moment. In the same solvent, equimolar addition of R_(3)N and SO_(3) produce a substance having an almost identical dipole moment. Reason (R) : Both HCI and SO_(3) are Lewis acids and can react with the amine base to form polar substances which undergo ionic dissociation in a solvent sufficiently more polar than benzene. Moreover, (N-S) bond is a more polar bond.

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

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
