Interpretation:
Fluoride works as a leaving group in the given nucleophilic
Concept introduction:
Substitution reactions are the reactions in which there is a replacement of an atom or a
The substitution reaction in which an electron seeking electrophile attacks an electron rich centre by replacing another electrophile is known as electrophilic substitution reaction. The substitution reaction in which a nucleus seeking nucleophile attacks an electron deficient centre by replacing another nucleophile is known as nucleophilic substitution reaction.

- Chemistry Please help explain this textbook question: Although N, N -dimethylaniline is extremely reactive toward electrophilic aromatic substitution and is readily substituted by weak electrophiles, such as diazonium and nitronium ions, this reactivity is greatly diminished by the introduction of an alkyl substituent in an ortho position.arrow_forwardAlkyl halides act as what in substitution reactions? Nucleophiles Electrophiles Catalysts Product E2 is bimolecular which means: both the nucleophile and the product take part in the step whose kinetics are measured both the nucleophile and the alkyl halide take part in the step whose kinetics are measured both the product and the alkyl halide take part in the step whose kinetics are measured None of the abovearrow_forwardComplete the table below indicating what is important in each category for an E1 or E2 reaction. E1 Rate Law Best Solvent Alkene geometry outcome How does electrophile substitution affection the reaction? Does leaving group ability affect the rate? Does base strength affect the rate? Does/how does base type affect product structure? E2arrow_forward
- e 2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH3OHarrow_forwardEnamines can serve as enolate surrogates in reactions at the a-carbon. In the reaction sequence, the structures of the enamine addition product – the initial zwitterion and its neutral tautomer – are shown. Draw the structures of the two reactants forming these intermediates, and draw the structure of the final product, obtained via hydrolysis of the neutral intermediate. initial zwitterionic intermediate neutral intermediate tautomerization Reactants H,0 hydrolysis product Draw the two reactants. Draw the hydrolysis product. Select Draw Rings More Erase Select Draw Rings More Erase H Harrow_forwardOnly one of these statements about nucleophilic aromatic substitution is true. O as the number of ortho and para electron withdrawing groups increases, the reaction rate decreases O the reaction proceeds by an addition-elimination mechanism the reaction involves a carbocation intermediate with delocalization of electrons all are falsearrow_forward
- For the given molecule, highlight any nucleophilic sites in red and any electrophilic sites in blue. O: 439 0-Harrow_forwardThe SN2 reaction shows a reversible mechanism when the basic strength nucleophile and leaving group are similar, but not when the strength of the nucleophile as a base is greater than that of the leaving group. Explain.arrow_forwardComplete the following nucleophilic substitution reactions. In each reaction, show all electron pairs on both the nucleophile and the leaving group.arrow_forward
