Which pair has permanent dipole moment for both the members?
Which pair has permanent dipole moment for both the members?
The correct option is B NO2 and O3
CO2 is a linear symmetrical molecule which looks like
O⇷=C⇸=O
Each one of the dipole moments cancel each other resulting in zero net dipole moment.
For SiF4 from VSEPR, ep = 4+42 = 4 i.e. tetrahedral geometry with 4 ligands and no lone pair.
∴ SiF4 is a symmetric molecule and will not have any dipole moment.
Thus, the answer is B.
NO2 looks like:
As you can see, there will clearly be a dipole moment because it looks like water and is also made up of different elements.
O3 looks like:
Ozone has a bent shape like water and thus, the individual dipole moments cannot cancel each other. The individual dipole moment is caused by resonance in the Ozone molecule which you have studied.
