Since ligroin is a nonpolar solvent (composed of 6-carbon alkanes), nonpolar sample molecules will easily dissolve in the solvent and not adsorb to the polar
Pentanol is an alcohol (a Which is more polar? Water, toluene, or cyclohexane? Which pair(s) of liquids will be miscible? (a) H_2O and CH_3CH_2CH_2CH_2CH_3 (pentane). (b) C_6H_6 (benzene) and CCl_4 (chloroform). (c) C_2H_5OH (ethanol) and CH_3COOH (acetic acid)...
Which of the following below explain why the alcohol is used in excess in this reaction. Note that there may be more than one answer. a. The alcohol is used in excess to make the reaction mixture sol Which of the following reactions would occur to a meas...
Answer:LiAlH4 can react with methanol in the same way as it reacts with water but less violently since the O-H bond in methanol is less polar.LiAlH4 + 4MeOH ---> LiOMe + Al(OMe)3 + 4H2Hence methyl alcohol is used in the quenching of LAH during workup. It is better to quench...
Arrange from least to most polar: Hexane, Toluene, Chlorocarbon, Ether, Ethyl Acetate, Acetone, Alcohol, and Acetic Acid In which of the following pure substances would hydrogen bonding be expected? a. ethyl b. alcohol c. ethyl methyl ether Which of the...
A. Which bond type is soluble in alcohol? 1. Metallic 2. ionic 3. polar 4. covalent, or nonpolar covalent bonds B. Which bond type has hard? 1. brittle 2. crystalsWhich of the following molecules has polar bonds and is nonpolar? A) HF \\ B) CO_2 \\...
Is it polar? Does heating up a solution make it less polar? Is ammonia, like water, strongly polar? Why or why not? What is the difference between polar protic solvents and polar aprotic solvents? What stereochemistry-antarafacial or suprafacial would form in a thermal (4 + 6) ...
Organic solvents like benzene, ether, and chloroform are neither protic nor strongly polar. What effect would you expect these solvents to have on the reactivity of a nucleophile in SN2 reactions? What alcohol is an isomer of dimethyl ether? *Express answer as a condensed structur...
Explain the mechanism of dehydration of alcohol. Why is NaHCO3 not so appropriate as a raising agent in the baking of bread? Why is yeast more suitable for the task of raising bread? What is acid/base catalysis? Give an example What i...
1. Write the mechanism of Fischer esterification of acetic acid with benzyl alcohol. Why is acetic acid more acidic than ethanol in terms of molecular structure? Please explain why the phenol -OH rather than the carboxylic acid -OH is acetylated by acetic anhydride. Hint: think about the ...
