Researchers at Cardiff University have overturned a century-old belief in organic chemistry by demonstrating that alkyl groups are not electron-donating, as traditionally thought, but rather electron-withdrawing compared to hydrogen. Using advanced computational methods, the study, published in Organic and Biomolecular Chemistry, revealed that alkyl groups pull electrons away from other parts of a molecule. This finding challenges long-standing textbook knowledge about the inductive effects of alkyl groups, which influences molecular properties and reactivity. Lead researcher Dr. Mark Elliott emphasized the need to correct textbooks and re-evaluate foundational concepts in chemistry to align with this groundbreaking discovery, which has implications across the field.

In general, if you enjoy reading this kind of scientific news articles, I would also be keen to connect with fellow researchers based on common research interests in materials science, including the possibility to discuss about any potential interest in the Materials Square cloud-based online platform ( www.matsq.com ), designed for streamlining the execution of materials and molecular atomistic simulations!
