Below is an ever evolving list links that I find useful or just wanted to include for some other reason, enjoy!
Enjoy the world of chemistry from Prof. Grenning's creative eye.
Prof. Mayr's database of nucleophilicities and electrophilicities is a wonderful resource!
The Bordwell pKa tables, maintained by Hans Reich, are a go to resource in thinking about problems of organic chemistry!
Prof. Lectka's website has a nice collection of bond strengths. It is so nice not to have to search for each of these.
