Nucleophile - Wikipedia
网页Nucleophilic describes the affinity of a nucleophile to bond with positively charged atomic nuclei. Nucleophilicity, sometimes referred to as nucleophile strength, refers to a substance's nucleophilic character and is often used to compare the affinity of atoms.
Nucleophilic substitution - Wikipedia
网页In chemistry, a nucleophilic substitution (S N) is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile).
7.1 Nucleophiles and Electrophiles - Chemistry LibreTexts
网页In both laboratory and biological organic chemistry, the most relevant nucleophilic atoms are oxygen, nitrogen, and sulfur, and the most common nucleophilic functional groups are water, alcohols, phenols, amines, thiols, and occasionally carboxylates.
Nucleophilic addition - Wikipedia
网页In organic chemistry, a nucleophilic addition (AN) reaction is an addition reaction where a chemical compound with an electrophilic double or triple bond reacts with a nucleophile, such that the double or triple bond is broken.
7.2: Nucleophiles - Chemistry LibreTexts
网页A nucleophile is an atom or functional group with a pair of electrons (usually a non-bonding, or lone pair) that can be shared. The same, however, can be said about a base: in fact, bases can act as ….
Nucleophiles and Electrophiles – Master Organic Chemistry
网页2012年6月5日 · When hydroxide ion donates a pair of electrons to an electrophilic atom (such as carbon here) to form a new covalent bond, it is acting as a nucleophile. And as we’ve seen before, when hydroxide ion donates a pair of electrons to an (acidic) proton to form a new covalent bond, we say it’s acting as a “ base “.
Nucleophile- What is it? - ChemTalk
网页A nucleophile is an electron-rich molecule that can form covalent bonds by donating electrons to electron-poor sites. Many molecules can act as a nucleophile in a chemical reaction, though some are stronger than others.
Nucleophile: Definition, Examples, and Strength - Chemistry Learner
网页A nucleophile is a reagent consisting of an atom, ion, or molecule that donates electron pair to form a bond. It is an electron-rich species that can be negatively charged or neutral with available electrons. A nucleophile reacts with an electrophile by donating electrons to form the bond [1-5]. N u c l e o p h i l e.
Nucleophile | Reactivity, Electrophiles, Substitution - Britannica
网页nucleophile, in chemistry, an atom or molecule that in chemical reaction seeks a positive centre, such as the nucleus of an atom, because the nucleophile contains an electron pair available for bonding.
Electrophiles and Nucleophiles - Definition, Types, Examples, …
网页A nucleophile is usually charged negatively or is neutral with a lone couple of donatable electrons. H 2 O, -OMe or -OtBu are some examples. Overall, the electron-rich species is a nucleophile. The word nucleophile is made from two words “Nucleo”, derived from the nucleus and “phile”, which means loving.
