Covalent bonding is a widely understood phenomenon that joins the atoms of a molecule by a shared electron pair. But in ...

A covalent bond is a shared pair of electrons ... Ionic compounds form what is known as a lattice structure. This is a regular arrangement of metal and non-metal ions which creates compounds ...

high surface tension relatively high viscosity All ionic lattices and polar covalent molecules are: soluble in water and other polar solvents insoluble in non-polar solutions (eg hexane ...

Chinese scientists proposed a novel imine-to-olefin transformation strategy to synthesize single-crystal sp² carbon-linked covalent organic frameworks (sp²c-COFs). COFs are crystalline ...
