In other words, it is an electron pair acceptor.
The"electron pairs" on sulfur are significantly delocalized in the pi electron system.
Methane has four bonding electron pairs.
In nickel carbonyl and other carbonyls, the electron pair on the carbon interacts with the metal; the carbon monoxide donates the electron pair to the metal.
BF3 is a Lewis acid because it accepts the electron pair from fluoride.
Aziridine is less basic than acyclic aliphatic amines, with a pKa of 7.9 for the conjugate acid,due to increased s character of the nitrogen free electron pair.
Nitrogen attracts the binding electron pair more strongly.
From the hydride electron pair, one electron is transferred to the positively-charged nitrogen of the nicotinamide ring of NAD(P)+, and the other hydrogen transferred to the carbon atom opposite this nitrogen.
The species that gains the electron pair is the Lewis acid;
Brønsted acid-base reactions are proton transfer reactions while Lewis acid-base reactions are electron pair transfers.
The acid and the base share the electron pair that formerly only belonged to the base.
A Lewis acid is a species that accepts a pair of electrons from another species; in other words,it is an electron pair acceptor.
In nickel carbonyl and other carbonyls, the electron pair on the carbon interacts with the metal;
RH2+ NAD+→ NADH+ H++ R; From the hydride electron pair, one electron is transferred to the positively charged nitrogen of the nicotinamide ring of NAD+, and the second hydrogen atom transferred to the C4 carbon atom opposite this nitrogen.
In chemistry, an electrophile is a reagent attracted to electrons that participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile….
A base is also defined as a molecule that has the ability to accept an electron pair bond by entering another atom's valence shell through its possession of one electron pair. .
Bases also directly act as electron-pair donors themselves:CO32-+ H+→ HCO3- NH3+ H+→ NH4+ A base is also defined as a molecule that has the ability to accept an electron pair bond by entering another atom's valence shell through its possession of one electron pair. .
The central boron atom in boric acid is electron deficient and accepts an electron pair, as for example in the next equation, from the oxygen in water to form the borate ion.
The species that gains the electron pair is the Lewis acid; for example, the oxygen atom in H3O+ gains a pair of electrons when one of the H-O bonds is broken and the electrons shared in the bond become localized on oxygen.
Replacement of a hydrogen atom in the ring's plane with the unshared electron pair, like in the ring's plane, located in the sp2 hybrid orbital, and not involved in an aromatic p-electron sextet.
In the oxygen- and sulfur-containing aromatic rings, one of the electron pairs of the heteroatoms contributes to the aromatic system(similar to the non-basic nitrogen-containing rings), whereas the second lone pair extends in the plane of the ring(similar to the basic nitrogen-containing rings).
