- Which of the molecules shown here will react faster as a diene in a Diels–Alder reaction with ethene? Explain.What is the majpr product resultring from the following series of reactions? The answer is B, please draw a detailed reactions with steps:)) Thanks!!For each pair of aromatic compounds, determine which will undergo electrophilic aromatic substitution faster. E,F,G,H only
- hi please help with: - most likely site of electrophilic aromatic substitution in each - major or minor compounds (explain the reason(s) that you made your choice) - rank the three compounds in increasing order of reactivity (number them as 1,2 and 3 being the most reactive)Draw the major E2 elimination products from each of the attached alkyl halides.If my elimination product is correct then what would the SN2 product be?
- Which nucleophile(s) is also a strong base? a) CH3MgBr b) LiAlH4 c) CHCH2OH d) Both CH3MgBr and LiAlH4What is the complete mechanism using curved arrow formalism of the two products shown below? Explain why one is major and the other is minor product formation.Please show all steps of the mechanism of this friedal crafts alcylation problem and show how the super electrophile was formed, thanks!
- What is the slow (rate-determining) step in any electrophilic aromatic substitution reaction? Please provide a detailed explanation.Shown below are two reactions; Reaction 1 is a Friedel-Crafts acylation while Reaction 2 is a Friedel- Crafts alkylation. State which reaction will occur faster and justify your answer, with words and structures. Explain these all: e- density / Deactivation / Resonance stable / faster the carbonation formed because it's gonna have smaller activation energyAlkyl diazonium salts (shown below) are considered "super" leaving groups; a consequence of this is that they tend to be contact explosives What quailities make alkyl diazonium salts such excellent leaving groups?
