Atomic Structure and Interatomic Bonding - Secondary bonding or van der Waals Bonding

10 important questions on Atomic Structure and Interatomic Bonding - Secondary bonding or van der Waals Bonding

Are van der Waals bonds stronger or weaker than primary bonds?

Weaker

Where does secondary bonding exist?

It exists in all atoms or molecules, but can be obscured by one of the primary bonding types.

Where does secondary bonding result from?

It results from the coulombic attraction between the positive end of one dipole and the negative end of an adjacent one, which is called a dipole interaction.

Where do dipole interactions occur?

Between induced dipoles, polar molecules and combinations of these.

Where can hydrogen bonding be found?

Between molecules that have hydrogen as one of the constituents.

How are dipoles created?

Vibrational motions in atoms can cause distortions of electrical symmetry and create small electric dipoles, which can induce/create more dipoles.

What can induced dipole bonding enable in inert gases?

The liquefication and solidification in inert gases.

How do permanent dipole moments exist?

In polar molecules by an asymmetrical arrangement of positively and negatively charged regions.

What is a consequence of the hydrogen bond?

Really high melting and boiling temperatures.

What is the anomalous and familiar behaviour of water?

It expands upon freezing.
