Question

Predict whether N₂ is likely to have a relatively high or low boiling point.

	high
	low

Answer 1

In order to do this we need to follow this steps:

Step 1: Classify each substance as either a metallic element, carbon in the diamond form, another nonmetallic element, an ionic compound, or a molecular compound.

In this case, we have a diatomic molecule N2, non metal.

For molecular compounds, draw the Lewis structure for the molecule.
In this case, it would be N N, and both N with a lone pair.

Step 3: If there are no O-H, N-H, or H-F bonds, determine the polarity of the bonds.
In this case, both molecules will go to the lone pair of electrons, so, it's non polar.

Step 4: Predict whether the polar bonds are symmetrically or asymmetrically arranged.
It's a non polar molecule, therefore, it does not have polar bonds.

Step 5: For substances that contain particles of about the same size, the substances with chemical bonds (ionic, covalent, or metallic) have stronger attractions between particles than substances with intermolecular attractions (hydrogen bonds, dipole-dipole attractions, or London forces). Chemical bonds are generally stronger than intermolecular attractions.

In this case, we have a london force in N2 molecule, and it's covalent bond.

With all of this, we can predict and say that this molecule will have a low boiling point.

Hope this helps
