If the Earth's radius suddenly shrank by a factor of 2 but the Earth's mass remained unchanged, how much would you weigh while standing on the new (smaller) surface of the Earth? (a) 16 times as much. (b) 4 times as much. (c) Twice as much. (d) Half as much. WebIn the presence of strong nucleophiles, benzene can do a Nucleophilic Aromatic Substitution, also called S N AR. Unlike EAS, where addition is initiated by the presence of a strong electrophile, addition-elimination can also be initiated by a strong nucleophile in the presence of a good aryl leaving group. Concept #1: General Mechanism.

WebOne possible way to do a substitution on pyridine is nucleophilic aromatic substitution. Even with no catalysts, the nitrogen atom, being electronegative, can hold the negative charge by itself. Another way is to do an oxidation before the electrophilic substitution. WebWhich halogens are synthetically useful in halogenation of an aromatic ring? Cl2. Br2. Select all reagents necessary for the bromination of benzene via an electrophilic aromatic substitution reaction. FeBr3. Br2. Complexation of Br2 with FeBr3 _____ and _____ the Br-Br bond to generate a stronger electrophile.
WebNucleophilic substitutions can take place in aromatic compounds when an electron rich nucleophile attacks an electron deficient aromatic ring and replaces a leaving group.
