what is an electron pair acceptor? electron pair donor?

Answer 1

electron pair acceptor is a substance or impurity which can join to an already existing chemical element, by accepting a electron from it.eventually,the chemical structure of the chemical element is now complete..since it has donated the extra electron pair to the'acceptor'..

Answer 2

Electron Pair Acceptor

Answer 3

An electron-pair acceptor is a Lewis Acid an an electron-pair donor is a Lewis Base. Lewis broadened the Bronstead-Lowry definition of acids and bases yet all proton donors are nonetheless acids accoording to the Lewis Definition and all proton acceptors are bases. After the Lewis definition got here, acids no longer necessary to have a detachable hydrogen ion. Electron pair donirs are especially compounds with Nitrogen and Oxygen. the oxygen on water is bonded to 2 hydrogens in spite of if it may easily donate yet another electron pair to a proton and tackle an outstanding can charge because of the fact it 'owns' fewer electrons. the 1st 2 hydrogens each and every contributed an electron to the bond and oxygen became nonetheless neurtal yet whilst oxygen has to make contributions the two electrons, its can charge will boost via one, and it turns into H3O+. Nitrogen does the comparable ingredient in ammonia whilst it turns into the ammonium ion. The H+ ion is an electron acceptor because of the fact it incredibly is purely a proton without electrons in spite of if it nonetheless has an empty s orbital which could accomodate 2 electrons. BH3 is likewise an electron pair acceptor because of the fact the Boron has an s orbital and p orbital, each and every p orbital can carry 3 electron pairs and can be seen 3 orbitals, px, py, pz, and the s can carry one pair (4 altogether) yet there are purely 3 electron pairs in BH3 considering there are 3 bonds and no lone pairs. it incredibly is good the way it incredibly is in spite of if it has an empty orbital and could accomodate one greater electron pair. H- with 2 electrons can donate the pair to the empty orbital and sort BH4.

Answer 4

An electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process.

A terminal electron acceptor is a compound that receives or accepts an electron during cellular respiration or photosynthesis. All organisms obtain energy by transferring electrons from an electron donor to an electron acceptor. The process starts with the transfer of an electron from an electron donor. During this process (electron transport chain) the electron acceptor is reduced and the electron donor is oxidized. Examples of acceptors include oxygen, nitrate, iron (III), manganese (IV), sulfate, carbon dioxide, or in some microorganisms the chlorinated solvents such as tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethene (DCE), and vinyl chloride (VC). These reactions are of interest not only because they allow organisms to obtain energy, but also because they are involved in the natural biodegradation of organic contaminants. When clean-up professionals use monitored natural attenuation to clean up contaminated sites, biodegradation is one of the major contributing processes

Answer 5

Acceptor: electrophile or Lewis acid.

Donor: nucleophile or Lewis base.
