- Give a mechanism for the following Copper-catalysed Azide-Alkyne Cycloaddition of phenylacetylene and organic azidesSN1 substitution and E1 elimination frequently compete in the same reaction.(a) Propose a mechanism and predict the products for the solvolysis of2-bromo-2,3,3-trimethylbutane in methanolAcetoxybenzene (PhOC(=O)OCH3) is much less reactive than ethoxybenzene (PhOCH2CH3) in electrophilic aromatic substitution reactions. Suggest an explanation for this result, based on an analysis of the inductive and resonance electronic effects of the two substituents on the stability of theWheland intermediate for para substitution by an electrophile E+

Use resonance forms to show how the cyano group activates the double bond for conjugate addition.(ORGANIC CHEMISTRY) (mechanisms) please give a answer for the following mechanism. Provide a detailed stepwise mechanism for the following transformation.Please let me know the mechanism of 'thermal sigmatropic rearrangement of allyl phenyl ether'
- please provide full organic mechanism for the attached reaxtions using proper arrows, lone pairs and charges.Propose a mechanism for the following reactionExplain the following observation. Treatment of alkyl chloride A with NaOCHCH3 yields only one Hint product B, whereas treatment of A with very dilute base in CH,CH,OH yields a mixture of B and C, with C predominating. Select the single best answer. Solution CI Guided Solu nces B Some of the carbocation intermediate of the E2 mechanism rearranges, leading to a second product. Using dilute base allows a byproduct to form via the Sy2 mechanism. The antiperiplanar requirement of the El mechanism causes two products to form. Switching from concentrated to dilute base shifts the mechanism from E2 to El.
