benzaldehyde to arylbenzyloxyhydrosilanes at room temperature. The products were obtained in yields up to 97 %. The nucleophilicity of the catalyst was demonstrated to be critical via a stereo-electronic map and a Lewis base activation mechanism with a hypervalent silicon intermediate species was ...
Draw the Lewis structure for NO2-. Predict the electron geometry and molecular geometry and state whether it is polar or nonpolar.Draw and explain the Lewis structure of SeF2. Determine its molecular geometry, hybridization, bond angles, and pola...
Meanwhile, Lewis structures are commonly used to represent covalent bonding as lines or as pairs of dots between two elements (i.e., shared electron pairs). Answer and Explanation: a) The nitrite ion (NO{eq}_2 ^- {...
A phosphono group refers to a chemical group where the phosphorous atom is linked to a sugar carbon atom or the phosphonate moiety is connected to the sugar through a C-C bond. It is utilized as a mimic of sugar phosphates and offers stability against hydrolysis compared to labile phosphate...
As used herein, the term “cleavable linking arms” refers to linking arms, which are a chemical group or a covalent bond which covalently attaches at one end to a solid support and at the other end to ibogaine or noribogaine. At least one of the covalent bonds of the linking arm whic...

In contrast, the chemistry of NO release from S-nitrosothiols is very complex. This class of compounds (general formula RSNO) contain a nitroso group attached by a single chemical bond to the sulphur atom of a thiol, where R denotes a cysteine-containing peptide (Patel et al.2017). S-Nit...
