Title: what is the name of the intermolecular force holding NO2? WHAT??
Post by: appleseed on February 28, 2009, 11:43:08 PM

The questions is what is the name of the intermolecular force holding NO2?
the molecule IS NOT polar!! Therefore its VAn Der waals forces!! how can the answer  it gives me be dipole dipole
same with N2O4 not polar

have i got something wrong?

Why do you think NO₂ is non-polar?

the molecule is symmetrical

But water, H₂O is also symmetrical, and polar?

CO₂, carbon dioxide, is also symmetrical but non-polar...

Whilst you may be on to something with the symmetry argument, it's not the complete story.

NO2 has polarity .Now decide which type of IMF present in it ?
