(a)
Interpretation:
The curved arrow mechanism for the given reaction that can be used to form three-membered rings is to be predicted.
Concept introduction:
The curved-arrow notation is used to show the transfer of electrons from one atom to another. The curved arrow has two barbs (head and tail) which represent the direction of electron flow.
The chemical name of glycidic ester is

Acidic hydrogen is defined as hydrogen that carries positive charge when the acid dissociates. The acidity in esters depends upon the stability of enolate ion. The higher is the stability of enolate ion higher is the acidity.

- (i) Explain why a high reaction temperature favours elimination reactions, instead of substitution reactions. (ii) Explain why polar aprotic solvents favour Sn2 reaction but not favour SN1 reaction.arrow_forward(a) Discuss the aromaticity of a six membered heterocyclic compound which is weak base in nature. (b) Discuss about the stability factors of the reaction intermediates, which involved in a name reaction "Wittig rearrangement".arrow_forwardThe saccharide shown here is present in some plant-derived foods. (a) Indicate the anomeric carbon atom(s) in this structure by drawing a circle around the atom(s) or by drawing an arrow pointing to the atom(s). (b) Would this saccharide give a positive result with Benedict’s reagent? Why or why not? (c) Would this saccharide give a positive result with Barfoed’s reagent? Why or why not? (d) Would this saccharide give a positive result with Seliwanoff’s reagent? Why or why not? (e) In a separate set of experiments, the saccharide solution was treated with a reagent that breaks glycosidic bonds. After this treatment, would any of the three assays give different results? Be sure to indicate which assay results would be different and give a reason.arrow_forward
