Debunking a core chemistry concept taught in classrooms everywhere

Phys · · 269 words · By Newcastle University

Researchers from the University of Newcastle, University of Cardiff, and University of New England have published a study in the Journal of Chemical Education challenging the traditional 'inductive effect' explanation in chemistry. The authors propose a new conceptual framework based on modern computer modeling to improve the accuracy of chemistry education and research.
