(b)
Interpretation:
The major product formed when the given amines is treated exhaustively with methyl iodide and then heated with
Concept introduction:
Amines are the organic compounds that are formed by replacement of hydrogen from ammonia. Amines are basic in nature because the nitrogen can donate its lone pairs and it also has the ability to accept proton in water.

EBK ORGANIC CHEMISTRY
- A carboxylic acid has two oxygen atoms, each with two nonbonding pairs of electrons. (b) Compare the resonance forms with those given previously for an acid protonated on thecarbonyl oxygen atom.(c) Explain why the carbonyl oxygen atom of a carboxylic acid is more basic than thehydroxy oxygen.arrow_forwardExplain the following statements. You must use chemical equations to justify your explanation. (ii) (I) Phenol is more acidic than cyclohexanol.arrow_forwardArrange each group of compounds in order of increasing acidity.(c) benzoic acid, o-nitrobenzoic acid, m-nitrobenzoic acidarrow_forward
- Provide the reagents and solvents (where appropriate) needed to bring about the following transformations. (a) CI (b)arrow_forward- Rank the following substances in order of increasing acidity: (a) Phenol, p-methylphenol, p-(trifluoromethyl)phenol (b) Benzyl alcohol, phenol, p-hydroxybenzoic acidarrow_forwardShow how you can synthesize the following compounds starting with benzene, toluene, and alcohols containing no morethan four carbon atoms as your organic starting materials. Assume that para is the major product (and separable fromortho) in ortho, para mixtures.(a) pentan-1-amine (b) N-methylbutan-1-aminearrow_forward
- (a) Give chemical tests to distinguish between the following pairs of compounds :(i) Pentan-2-ol and Pentan-3-ol (ii) Methanol and Phenol(b) o-nitro phenol is more acidic than o-methoxy phenol. Explain why.arrow_forward(a) (b) Briefly explain why the alpha hydrogens of carbonyl compounds are much more acidic than typical C-H bonds, such as those in methane. Predict the structure of the product formed in the following reaction. Explain your reasoning. ن PPh3arrow_forwardPredict the major product when each reagent reacts with ethylene oxide.(a) NaOCH2CH3 (sodium ethoxide) (b) NaNH2 (sodium amide)arrow_forward
- (a) Although phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol. Give two reasons.(b) How will you bring about the following converstions?(i) Propanone to propane (ii) Benzoyl chloride to benzaldehyde(iii) Ethanal to but-2-enalarrow_forwardSafrole, which is isolated from sassafras (Problem 21.33), can be converted to the illegal stimulant MDMA (3,4- methylenedioxymethamphetamine, “Ecstasy”) by a variety of methods. (a) Devise a synthesis that begins with safrole and uses a nucleophilic substitution reaction to introduce the amine. (b) Devise a synthesis that begins with safrole and uses reductive amination to introduce the amine.arrow_forwardSafrole, which is isolated from sassafras (Problem 21.33), can be converted to the illegal stimulant MDMA (3,4-methylenedioxymethamphetamine, "Ecstasy") by a variety of methods.
