I have been Searching and listing some cool online tools for chemistry (free). Please tell me what are available on the net. Here is what I have already used:
1. Webqc.org : About 20 online calculators in chemistry like gas laws etc. Old website, looks old too.
2. http://www.calistry.org : About 50 calculators in chemistry, looks modern and is pretty handy but does not shows up in google frequently.
3. http://web.chemdoodle.com/demos/iupac-naming : IUPAC nomenclature, wow kind of tool !
Please let me know other tools!!
