Question

The gas nitrogen N-N and carbon monoxide CO isoelectronic that is they have the same number of electrons int their molecules. Suggest why N-N has a lower boiling point than CO

Answer 1

The bond isn't as strong.

Answer 2

What "bonds"? Discuss the type of intermolecular forces that hold each of them together (covalent), as well as the dipoles that may result....

Answer 3

N-N is induced dipole dipole I'm not sure

Answer 4

So has weaker bond than CO

Answer 5

You have convalent, london-dispersion...

Answer 6

The good question is:
Suggest why CO has a higher boiling point than NN

Answer 7

When talking about boiling points we are talking mostly about intermolecular interactions!



A lower boiling point is characteristic of weaker intermolecular interactions

Answer 8

N2 is non-polar as it is made up of the same elements and thus sharing of electrons is about even (both atoms in N2 have the same electronegativity). Whereas with CO, oxygen has a greater electronegativity than Carbon, therefore electrons will hang around the oxygen more making the oxygen have a partial negative charge and the carbon have a partial positive charge
