Strength of Bonds

Postby Reese - Dis 1G » Fri Nov 09, 2018 11:42 am

Is the boiling/melting point affected by the strength of the bonds? If so, how?

I believe that it is because the stronger the bond, the harder it is to break resulting in a higher boiling and melting point.

^ Yes, the stronger the bond the more energy it will take to break it resulting in a higher boiling point.

Intermolecular forces determine boiling point, but I don't believe intramolecular forces (bonds) do.

Stemming from what the last post said, if you were to melt ice, it is still H2O so the intramolecular molecules are not affected. The state of the H20 is affected though...that shows a change in intermolecular forces.

Boiling and melting are both physical changes, not chemical changes. Therefore the intermolecular forces are at play - if the intramolecular forces were affected then it would be a chemical change.

Are we going to have problems where we have to calculate the strengths of bonds?

For now, I do not think we need to. However, you should at least conceptually know that triple bonds are stronger and shorter than single bonds

The stronger the bond, the higher the melting/boiling point.

I don't believe we do but usually the more bonds there are, the shorter each bond is and the stronger they are altogether.
