Is a compound considered a pure substance? Why or why not? Why are ionic compounds electrically neutral? Why do nonmetals form covalent bonds? Use VSEPR to explain why BH_3, NH_3 \space and \space FCl_3 all have different shapes even though they all follow the general formula of AX_3...

Here, we rationally control the diffusion of the reactants to obtain suppressed proton supply and greatly enhanced nitrogen flux using proton-filtering covalent organic frameworks, forcing a highly selective and active nitrogen reduction. In this proof-of-concept system, we achieved a high performance...
A wide range of solid and fluid materials have been proposed for ammonia separation, such as activated carbon, covalent organic frameworks, deep eutectic solvents, ionic liquids, metal organic frameworks, oxides, and porous organic polymers [115,116,[118], [119], [120], [121], [122], [123...
The adduct H3B:NH3 formation occurs via the dissociation (BH3 + BH3) of diborane or via the complex H3BHBH2NH3 formation. Two transition states for the complex H3BHBH2NH3 formation from diborane and ammonia were found, which are an ionic and a covalent (keeping of one B-H-B bridge ...

Ab initio calculations on hypothetical organometallic cations Cp2Ln+(Ln = Sc, La) show bent metallocene structures are favoured due to the covalent σ bonding contributions involving the totally symmetric metaldσorbitals which favor bent structures. Although the contribution ofdσis lower thandπ, ...
Transition metal borides or simply MBenes are an emerging class of catalysts, still in infancy in the field of NRR. Owing to the strong M–B and B–B covalent bonds, these catalysts offer high chemical and thermal durability and provide a high active surface area as compared to metal nitrid...
