(a) Impure compounds tend to have lower melting points than pure samples. Explain why this occurs, using biphenyl as an example. Make sure you consider what happens upon melting in molecular terms. (b) Is recrystallization a suitable method for purifying all types of organic compounds? If not, why not?

Propose how the components of a mixture containing benzene, toluene, and water can be separated. Include how can you justify the effective separation of the components.
In the following three instances, which choice is greener in each situation? Explain. (a) Benzene as a solvent or water as a solvent.
MTBE, Methyl tert-butyl ether, CH3OC(CH3)3, is used as an oxygen source in oxygenated gasolines. MTBE is manufactured by reacting 2-methylpropene with methanol.(a) Using Lewis structures, write the chemical equation representing the reaction.(b) What volume of methanol, density 0.7915 g/mL, is required to produce exactly 1000 kg of MTBE, assuming a 100% yield?
(a) What is the difference between chlorofluorocarbons and hydrofluorocarbons?
Rubbing alcohol is often used as a disinfectant and sometimes as a component of handsanitizers. If you were to purchase a bottle of rubbing alcohol at a store, it would most likely sayisopropyl alcohol or isopropyl rubbing alcohol, although it is also called isopropanol. Ethylalcohol is also used in hand sanitizers, and is actually more commonly used. Why would a handsanitizer whose major component is ethyl alcohol evaporate more quickly than one whose majorcomponent is rubbing alcohol?
Explain the reaction between Methyl Salicylate with acetyl chloride (CH3COCl). Gives your answer in detail from the name of the reaction until the formation of the product. You are advised to give an illustration of the reaction.
1. Which IMF or IMFs are correlated with molar mass? Describe this correlation 2. Heptane, hexane, and pentane are hydrocarbons. Rationalize the evaporation data of these substances based the type(s) of IMFs present in each and the relative strengths of these. 3. Ethanol, methanol, 1-propanol, and 2-propanol are alcohols. Rationalize the evaporation data of these substances based the type(s) of IMFs present in each and the relative strengths of these. (Hint: How are these molecules alike and how are they different?) 4. 1-propanol and 2-propanol are isomers, substances having the same chemical formula. Is the evaporation data for these substances the same or different? If different, can you account for why this may be the case from a comparison of the Lewis structures of each substance and the IMFs present in each substance? Explain. 5. Acetone and 2-propanol are chemically interconvertible. Reduction (by the addition of the equivalent of H2) of acetone yields 2-propanol. Conversely,…
two of these statements are truths and one is a lie. Which of the following statements is a lie? Select one: a. The human blood follows the aspect of suspension because it contains different sizes of molecules. b. The proton concentration of seawater is 0.00000001 M therefore it is an acidic solution. c. Not all inorganic compounds do not have carbon atoms. Thus it is easier to say that these types of compounds, if compared with organic compounds, are not solely based on composition. guess of the student is A
Ethanol is miscible with water. Assuming that caffeine is soluble in ethanol, could you use ethanol as a solvent to extract caffeine from coffee, rather than using dichloromethane as the extraction solvent? Explain.
Consider propane (C3H8) and decane (C10H22): Which is soluble in water? Which has lower boiling point? Which has higher boiling point? Which has lower melting point? Which has higher melting point? Vaseline, a complex mixture of hydrocarbons is used as a skin lubricant and ointment. Explain why Vaseline is insoluble in water but soluble in dichloromethane, CH2Cl2.
