Interpretation: The differences observed in the IR and NMR spectra of 4-methyl-2-pentalol and the various methylpentenes in dehydration reaction needs to be explained.
Concept introduction: The analysis of the interaction of infrared light with a molecule is termed as infrared spectroscopy. The main use of infrared spectroscopy is the identification of
Nuclear magnetic resonance (NMR) is a spectroscopy technique that works on the basis that the nucleus of the atoms absorbs

- Which qualitative analysis test from this module can help distinguish between different kinds of ketones? Can this same test give a positive result for 4-methylacetophenone? Why?arrow_forward1) Based on the Material Safety Data Sheets (MSDS) for the compounds, which of the compounds in this experiment is the most hazardous, and why (you have been given a representative aryl halide rather than all of the alkenes – as the products are all new, there’s not a simple answer to gauge their potential hazard)? 2,3-dihydrofuran,2-Mercaptobenzimidazole,Selectfluor, Dimethylformamide,dichloromethane-methylene chloride.arrow_forward10) Write an equation for the reaction of n-propyl magnesium chloride and butanal (Not 3- methylbutanal). Why was it important to have dry equipment that was heated in oven and a drying tube placed on top of the condenser for the above-mentioned reaction? Explain?arrow_forward
- When equivalent amounts of methyl bromide and sodium iodide are dissolved in methanol, the concentration of iodide ion quickly decreases and then slowly returns to its original concentration. Account for this observation.arrow_forwardPlease answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. 1-butanol, 2-butanol, and diisopropyl ether all tested negatve (immiscible) in the solubility test with concentrated H2SO4. Considering the structure of the compounds, what generalization can be made for a substance to be soluble in concentrated H2SO4?arrow_forwardHow do you account for the observed solubility of naphthalene and sodium chloride in water and in ether based on the nature of the bonds that exist in them?arrow_forward
- Select a suitable solvent for analysis of one of these terpenes by UV spectroscopy. Explain your choice. Terpenes: Carvone, Carveol, and Pulegone a. ethyl acetate b. benzene c. chloroform d. hexanearrow_forwardThe question is: Provide a method for separating a mixture of benzophenone and tributylamine which is dissolved in diethyl ether. I don’t even know where to start for this question. Thanks!arrow_forwardAnalyze both IR and NMR spectra ,Identify the unknown (solid sample )? Note: the same unknown is used in the experiment to get both IR and NMR. The list of all the possible organic compounds are as follows: Cumene, 3-Methy-2-butanone, Phenethyl alcohol, Isopropyl Acetate, Ethel benzoate, 3-phenylpropionaldehyde, isobutyl cinnamate, cyclamen aldehyde, Styrallyl acetate, Butyl butyrate, propiophenon, phenylacetylene, Cis-Hexenyl-3-Acetate, Benzyl propionate, 3-(p-ethyl-phenyl)-2,2-dimethyl propionaldehyde, 2-methoxy-4-ethyl-phenol, P-ethylphenol, diphenyl amine, 4-phenyl-3-buten-2-one, Diethyl Terphthalate, glutaric acid, cinnamic acid, P- ethylbenzoic acid, Coumarin, vanillin, (2,2,2-trichloro-1-phenylethyl)acetate, 4-(p-hydroxyphenyl)-2-butanone, 2-ethoxy-5-prop-1-enylphenol, t-butyl-phenol, Thymol, Calone, Syringol, Syringaldehyde. Borderline MP unknowns: Styrallyl alcohol, 1,1-dimethyl-2-phenethyl acetate, 1,1-dimethyl-2-phenyl ethanol.arrow_forward
- what is the purpose of saturated sodium bicarbonate solution does during the purification of synthesized bromobutane?arrow_forwardWhat is the theoretical yield and limiting reagent for the reaction of benzophenone with sodium borohydride to form diphenyl methanol as described in the experiment provided if you begin with 1.75g of benzophenone in 25 mL of 95% ethanol and add 0.75 g of sodium borohydride portion wise over 45 minutes?arrow_forwardExplain the function of using dichloromethane after the steam extraction of Eugenol. Also discuss if there are any differences and which ones in soxhlet extraction and steam drag.arrow_forward
