Concept explainers
Interpretation:
The given order of reactivity has to be accounted.
Concept Introduction:
The increasing stability order of carbocation is as follows,
Primary carbocation < secondary carbocation < tertiary carbocation
Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation. Nucleophilic nature depends on the negative charge present in the molecule, the solvent in which it present and the electronegativity of the atom.
Leaving group: it is the fragment that leaves the substrate in a

- Enamines normally react with methyl iodide to give two products: one arising from alkylation at nitrogen and the second arising from alkylation at carbon. For example, Heating the mixture of C-alkylation and N-alkylation products gives only the product from C-alkylation. Propose a mechanism for this isomerization.arrow_forwardA problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forwardNonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forward
- A) Provide the reagent and reaction mechanism to show how the reactants and products in the following reaction can interconvert B) under what conditions would the reaction I) favour reactants, II) favour the products and III) why?arrow_forwardProvide reagents/conditions to accomplish the following syntheses. More than one step is required in some cases.arrow_forwardShow how the following starting materials are converted to the givenproduct by a series of two pericyclic reactions. Account for the observedstereochemistry.arrow_forward
- The treatment of (CH3)2C=CHCH2Br with H2O forms B (molecular formula C5H10O) as one of the products. Determine the structure of B from its 1H NMR and IR spectra.arrow_forwardIn an aqueous solution containing sodium bicarbonate, aniline reacts quickly withbromine to give 2,4,6-tribromoaniline. Nitration of aniline requires very strong conditions,however, and the yields (mostly m-nitroaniline) are poor.(a) What conditions are used for nitration, and what form of aniline is present under theseconditions?arrow_forwardThe reaction of bromomethylcyclopentane in methanol and heat generates a complex mixture of products and consisting of the following five compounds. Propose mechanisms that explain these productsarrow_forward
