Electronegativity and molecular polarity are central to understanding chemical bonding. By combining periodic trends with molecular geometry, you can predict whether a molecule is polar or nonpolar.

Molecular polarity and intermolecular forces explain why substances dissolve, boil, or stick together the way they do. From the shape of a molecule to the pull of its atoms, polarity determines ...

Chemists at the Max-Planck-Institut für Kohlenforschung have developed a practical two-step method for alkylating alkenes via ...

Sugar-based amphiphilic molecules, which contain a hydrophilic sugar headgroup and a hydrophobic segment such as an alkyl chain, can assemble in water depending on their concentration, forming ...

Drew Szabo from the Centre of Excellence in Mass Spectrometry at the University of York, UK discusses his talk at HTC-19, ...

You can feel wet when you can see water and when you can’t see water. You can also feel dry even when there’s a lot of water ...

Chemists at the Max-Planck-Institut für Kohlenforschung have solved a decades-old synthetic puzzle, developing a practical, two-step method for the alkylation of alkenes via thianthrenation. The ...

Synthetic materials rarely mimic the dynamic helicity observed in biological systems like DNA and proteins, often forming ...

The resulting stiff and durable material could lead to strong, long-lasting, natural-rubber composite tires that reduce waste ...

A chlorophyll-based polymer shows stepwise evolution from nonhelical to helical structures, offering a new route to adaptive ...
