Propose a method to separate a mixture containing phenol, benzoic acid, naphthalene, and p-nitroaniline. Phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in either sodium hydroxide or sodium bicarbonate solutions. Write out the structures of the molecules in your scheme.
how do you separate three organic substances by means of extraction. If the three substances, one is 4-methoxyphenol, one acid, the other substance, 1-phenylethylamine, is a base and the third substance, 1,4-dimethoxybenzene, lacks acid-base properties. The three substances are dissolved in diethyl ether, which is a relatively non-polar organic solvent

O aldehydes are more reactive toward nucleophiles than ketones. Onucleophilic attack occurs preferentially at the less hindered carbon of the formyl group.

20. Some alcohols undergo rearrangement or other unwanted side reactions when they dehydrate in acid. Alcohols may be dehydrated under mildly basic conditions using phosphorus oxychloride (POCI3) in pyridine. The alcohol reacts with phosphorus oxychloride much like it reacts with tosyl chloride, displacing a chloride ion from phosphorus to give an alkyl dichlorophosphate ester. The dichlorophosphate group is an outstanding leaving group. Pyridine reacts as a base with the dichlorophosphate ester to give an E2 elimination. Propose a reasonable mechanism for the dehydration of 2- methylcyclohexanol by POCl 3 in pyridine.
