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

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

Re: Strength of Bonds
Intermolecular forces determine boiling point, but I don't believe intramolecular forces (bonds) do.

Re: Strength of Bonds
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.

Re: Strength of Bonds
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.

Re: Strength of Bonds
Are we going to have problems where we have to calculate the strengths of bonds?

Re: Strength 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

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