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 functional groups. The theory on which IR spectroscopy works is that absorption specific
Nuclear magnetic resonance (NMR) is a spectroscopy technique that works on the basis that the nucleus of the atoms absorbs

- Explain 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_forwardWhy is the 4-methoxyphenyl acetate organic layer subjected to washes with saturated sodium bicarbonate solution, water and brine when carrying out a separatory funnel extraction?arrow_forwardWhat might have been the product ratios observed in this experiment if an aprotic solvent such as dimethyl sulfoxide had been used instead of water?arrow_forward
- Sodium hydroxide was used to help separate benzoic acid and fluorenone because deprotonated benzoic acid (sodium benzoate) favorably partitions into the aqueous phase (and fluorenone does not). Would this procedure have worked without the sodium hydroxide (using simply neutral water)? Why or why not?arrow_forwardwhat will happen to the reaction of acetone in the sodium nitroprusside Test and in the iodoform test? what will happen if liquid Benzaldehyde is exposed into the air?arrow_forwardDraw complete mechanisms that explain the resultant product distributions observed for the reactions of tert-butyl alcohol and 1-butanol under the reaction conditions of this experiment.arrow_forward
- Briefly explain the electronic effect of the substituent present in p-methoxybenzoic acid as compared to benzoic acid.arrow_forwardRegarding an organic chemistry laboratory experiment: a. Why is it necessary to isolate eugenol from cloves using (direct) steam distillation rather simple distillation? b. In this experiment, why does eugenol distill at a temperature far below its boiling point? c. Why is diethyl ether used to extract eugenol from the distillate rather than ethanol?arrow_forwardIn this experiment, you preformed an extraction to separate the aqueous and organic solvent layers. Why was the organic solvent layer on the bottom in the separatory funnel? What would cause the organic solvent layer to be the top layer? Explain your answer.arrow_forward
- Explain the elution sequence (GLC) of: mesitylene<1-phenylethanol<acetophenone.arrow_forward2. In this experiment, you used ethyl acetate as the initial solvent to dissolve your mixture of benzoic acid, 4-bromoacetophenone and ethyl 4-aminobenzoate. i) Explain 3 reasons why ethyl acetate a good choice for this process? ii) Would you have obtained similar results with A) chloroform, B) ethanol, or C) water? Why or why not? Explain. Hint: Think about both solubility and miscibility of solvents when answering your question.arrow_forwardIn the grignard reaction, preparation of triphenylcarbinol, what is the melting point in this experiment?arrow_forward
