General rules 1) Activating (o,p) groups (+R, +I) win over deactivating (m) groups (-R,-I) 2) Resonance groups (+R) win over inductive (+I) groups 3) 1,2,3-Trisubstituted products rarely form due to steric crowding 4) With bulky directing groups, there will usually be more p-substitution than o-substitution 5) The incoming group replaces a hydrogen. SUBSTITUTION REACTION. In a substitution reaction, a functional group in a particular chemical compound is replaced by another group. Reagent Substrate Reactive intermediate Type of organic substitution. Nucleophilic Aliphatic Carbocation Aliphatic nucleophilic substitution. Electrophilic Aromatic Substitution (EAS) is a substitution reaction usually involving the benzene. ring; more specifically it is "a reaction in which the hydrogen atom of an aromatic ring is replaced as a. consequence of electrophilic attack on the aromatic ring." (Thinkbook). Benzene is best.

General rules 1) Activating (o,p) groups (+R, +I) win over deactivating (m) groups (-R,-I) 2) Resonance groups (+R) win over inductive (+I) groups 3) 1,2,3-Trisubstituted products rarely form due to steric crowding 4) With bulky directing groups, there will usually be more p-substitution than o-substitution 5) The incoming group replaces a hydrogen. The Mechanism for Electrophilic Substitution Reactions of Benzene is the key to understanding electrophilic aromatic substitution. You will see similar equations written for nitration, sulphonation, acylation, etc., with the major difference being the identity of the electrophile in each case. SUBSTITUTION REACTION. In a substitution reaction, a functional group in a particular chemical compound is replaced by another group. Reagent Substrate Reactive intermediate Type of organic substitution. Nucleophilic Aliphatic Carbocation Aliphatic nucleophilic substitution. 8 Nucleophilic Substitution and Elimination Reactions pair. Reagents that acquire an electron pair in chemical reactions are said to be electrophilic ("electron-loving"). We can picture this in a general way as a heterolytic bond breaking of compound X:Y by an electrophile E such that E becomes bonded to Y by the electron pair of the XY bond. Thus. After this discussion of the historical basis of the theory of aromatic electrophilic substitution, we will now deal with the recent work Which has supplied the experimental basis for the two-stage mechanism of this type of reaction.Electrophilic Aromatic Substitution (Aromatic compounds) aromatic substitution reactions in two ways: 1) reactivity . Mechanism for Friedel-Crafts alkylation. If a catalyst and heat is used, Electrophilic Aromatic Substitution occurs: reactions. A. Friedel-Crafts Alkylation. Mechanism: Step 1: Make electrophile. Step 2,3. Electrophilic Aromatic Substitution (EAS) is a substitution reaction usually involving the EAS reactions all follow the same general two-step mechanism. ) A General Mechanism for Electrophilic Aromatic Aromatic compounds undergo electrophilic aromatic substitution PDF Creator - PDF4Free v The mechanism of electrophilic aromatic substitution involves an initial rate determining Some common electrophilic aromatic substitution reactions are.
