Hi, in the first part of this question we have to find the which one of these have strongest dispersion force.
00:06
So, if we see this molecule carbon monoxide, there is a electronegativity difference between these two atoms.
00:14
Oxygen is more electronegative and carbon is less electronegative.
00:18
So, this molecule is polar and here is dipolar -dipolar interaction present.
00:33
Whereas, if we talk about hf molecule, it is also a polar molecule because fluorine is more electronegative than hydrogen.
00:48
So, it is polar molecule.
00:51
Here dipolar -dipolar intermolecular force will present and also hydrogen bonding will also present.
01:04
And nacl is a ionic compound.
01:13
So, here electrostatic interaction will present.
01:24
And if we talk about cl2, so here is no electronegativity difference.
01:31
So, it is nonpolar and here only dispersion force present.
01:47
So, that's why cl2 is the only molecule from the given option have strongest dispersion force...
