Cycloaddition reactions represent a cornerstone of synthetic organic chemistry, facilitating the formation of cyclic structures through concerted pericyclic processes. Traditionally explained via ...

Single-atom catalysts (SACs) comprise individual metal atoms—such as palladium (Pd), or platinum (Pt)—anchored on a high-surface-area solid support, which both isolates the metal and influences its ...

SP hybridization occurs when one s orbital and one p orbital from the same atom combine to form two new orbitals of equal energy. These new orbitals are linearly oriented 180 degrees apart, leading to ...

Electron orbitals show where and how electrons move around atomic nuclei and molecules. In modern chemistry and physics, they have proven to be a useful model for quantum mechanical description and ...
