Question

3. Which of the following is the correct order of
dipole moment?
(1) XeF2 > XeO3F2
(2) BF3 > BC13
(3) PC13F2 < PF3Cl2
(4) NH3 < NF3​

Answer 1

The correct decreasing order of dipole moments for the given molecules is BF3, NF3, and NH3.

So the correct order of decreasing dipole moment is NF3 < NH3.

What is a dipole moment?

• In electromagnetism, different kinds of charges give rise to dipole moments.
• When there are different charges in an electromagnetic system then a dipole moment arises.
• Dipole moment takes place in ionic and covalent bonds.
• The symbol of dipole moment is μ and it represents the molecular polarity.
• Moreover, it also tells about the charge separation and charge magnitude in a system.

So, the correct option is (4): NH3 < NF3​
