This is my go to resource for teaching IB HL Chemistry. I have been teaching for the past 19 years and I can say this is by far the best resource that I have ever taught with. The website taught me how to efficiently teach with the most clarity. My IB...

Quote of the day
I would like to emphasise strongly my belief that the era of computing chemists, when hundreds, if not thousands of chemists will go to the computing machine instead of the laboratory for increasingly many facets of chemical information, is already at hand. There is only one obstacle, namely that someone must pay for the computing time.

- Geoff, (not Richard!) I fear I am becoming more like my parents everyday, mixing up names of people that I clearly should not mix up....The Richard Thornley videos above must have confused me. John
- Hi John, You make a valid point (to Richard?) about HF and BF3 - although fluorine with an electronegativity value of 4 is always a problem with the ~ 1.8 rule of thumb - but I'm still not convinced that triangular bonding...
- Hello Omar, I'm a chemist, not a physicist, and the question is hypothetical as absolute zero can never be reached. As I understand it particles at absolute zero would not possess translational or vibrational kinetic energy. All particles...
- Richard,Interesting points in the Pause for Thought. The lead chloride examples are particularly interesting. I do find the Triangle most useful for compounds involving Fluorine. If you use the delta EN> 1.8 rule, then students...
