Which of the following is a correct statement regarding electrophilic aromatic substitution? A. Many suitable electrophiles are unreactive and can be stored for long periods of time prior to use. B. The carbocation intermediate will lose a proton to regain aromaticity, usually from a position other than the site of the electrophilic attack. C. Formation of the carbocation intermediate has a high activation barrier due to loss of aromaticity. D. Reformation of the aromatic ring has a low activation barrier and therefore occurs slowly. E. The carbocation intermediate has several resonance structures and is negatively charged.
The rate of the reaction of methyl iodide with quinuclidine was measured in nitrobenzene, and then the rate of the reaction of methyl iodide with triethylamine was measured in the same solvent. The concentration of the reagents was the same in both experiments. a. Which reaction had the larger rate constant? b. The same experiment was done using isopropyl iodide instead of methyl iodide. Which reaction had the larger rate constant? c. Which alkyl halide has the larger kquinuclidine/ktriethylamine ratio
Consider the following reaction. What is the role of LDA? CH2CH3 CHCO Et 1. LDA, THF 2. CH3CH₂Br CHCO₂Et LDA acts as a nucleophile and is substituted by the THF. LDA acts as a base and removes a proton from the alpha carbon to form the enolate. LDA acts as an electrophile and adds to the alkyl halide so it is easier to substitute. LDA acts as an acid to protonate the carbonyl carbon to form a good electrophile.
How does increasing base, solvent, or alkyl halide or aptly halide + base affect or decreasing them affect the reaction rate for e2/e1 and sn2/sn1? Please provide examples
