Electrophile - Wikipedia
网页In chemistry, an electrophile is a chemical species that forms bonds with nucleophiles by accepting an electron pair. [1] Because electrophiles accept electrons, they are Lewis acids. [2] Most electrophiles are positively charged, have an atom that carries a partial positive charge, or have an atom that does not have an octet of electrons.

Electrophile | Reactivity, Reactants & Electron-Pair | Britannica
网页electrophile, in chemistry, an atom or a molecule that in chemical reaction seeks an atom or molecule containing an electron pair available for bonding. Electrophilic substances are Lewis acids (compounds that accept electron pairs), and many of them are Brønsted acids (compounds that donate protons). Examples of electrophiles are hydronium ...
7.1 Nucleophiles and Electrophiles - Chemistry LibreTexts
网页Consider two hypothetical S N 2 reactions: one in which the electrophile is a methyl carbon and another in which it is tertiary carbon. Because the three substituents on the methyl carbon electrophile are tiny hydrogens, the nucleophile has a relatively clear path for backside attack.

Electrophile: Definition, Strength, and Examples - Chemistry Learner
网页An electrophile is a reagent consisting of an atom, ion, or molecule that accepts electron pair to form a bond. It is an electron-deficient species that can be positively charged or neutral with vacant orbitals. An electrophile reacts with a nucleophile by accepting electrons through addition and substitution reactions.

网页Tim Soderberg. University of Minnesota Morris. Next, we turn to electrophiles. In the vast majority of the nucleophilic substitution reactions you will see in this and other organic chemistry texts, the electrophilic atom is a carbon bonded to an electronegative atom, usually oxygen, nitrogen, sulfur, or a halogen.
Electrophile - an overview | ScienceDirect Topics
网页An electrophile is an electron-deficient species that reacts by accepting an electron pair to form a bond with a nucleophile, typically having a positive charge or an atom lacking a complete electron shell.
7.3: Formation of the Electrophile - Chemistry LibreTexts
网页The mechanism of electrophilic aromatic substitution follows two elementary steps. First, donation of a pair of π electrons to the electrophile results in a loss of aromaticity and formation of a cation. Second, removal of a proton from that cation restores aromaticity. How does the electrophile form in the first place?
