- Nitroethene, CH2CHNO?, is a very labile compound that must be prepared with care. Ifpurification of nitroethene s attempted, generally only small amounts are recovered, but theinner walls of the distillation apparatus are covered with a white film. Explain.If a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.The separation and purification processes given below and the method used against them are given. Which or which of these pairings are correct? I. Brewing of tea - ExtractionII. Purification of water impurities - ChromatographyIII. Separating olive pomace from olive oil while producing olive oil-DecantationIV.Petroleum fractions obtaining - Ordinary distillationV.

- When performing the extraction process for eugenol, what are the most common problems that can be encountered? Give at least two and give also the remedy/resolution to solve such problem.One of the components of nutmeg is an organic compound, Trimiristin, A. To extract this compound from nutmeg why we need to choose as a solvent, ether, and not acetone?B. Is it possible to choose water as an exhaustive solvent of Trimiristin?Good hand written solution with little bit explanation Asap Explain the liquid organic mixes of methanol, 1-propanal, and 1-butanol should be separated, identified and distinguished based on their volatilities. How to find the range of boiling points for the mixture of methanol, 1-propanol, and 1-butanol?
- Compound A is impure and has a melting point of 90°C - 98°C. After purification, A will most likely have a melting point of: *After purification via extraction, any organic substance should be rigorously dried; otherwise, its further purification via recrystallization will often fail to achieve the desired result. In a typical purification of an organic unknown, a solution of crude product in an organic solvent (i.e. diethyl ether) is what will remain following extraction. Suggest a simple means to remove small quantities of water from this solution.6 Assuming that hexane and water obey the required solubility criteria, why could they still not be used as a solvent pair in a mixed solvent recrystallization? Explain.
- The Dumas tube containing the volatile liquid vapor is removed from the boiling water bath and allowed to cool to room temperature when the volatile liquid has entirely vaporized.
