I have added new content to the bond order calculator mentioned at https://irthoughts.wordpress.com/2018/12/20/bond-order-calculator-tool/
The content added is to illustrate the risks of blindly relying on chemistry heuristics and old-school chemistry ideas. Essentially, it is debunked some few old-school chemistry ideas, like
- SO3 has a bond order of 2. Really?
- nitrogen cannot form five bonds. Really?
- octet rule expansion by means of using d orbitals. Really?
- bond order is the number of chemical bonds shared by two atoms. Really?
To access this content, visit http://www.minerazzi.com/tools/bond-order/calculator.php
Once there, navigate to the ‘What is computed?’ section, and then to the subsection ‘Beware of Blindly Relying on Chemistry Heuristics’.
Enjoy it.
