Answer the following questions following a Solubility and recrystalization lab for organic chemisty. 1. In a solubility and recrystallization lab you are working with the following chemicals : solids (benzoic acid, acetanilide,naphthalene, and resorcinol) and three solvents (water, ethanol and petroleumether) discuss and rank the polarity of the solvents and the polarity of the compounds being investigated. 2. Briefly describe how a mixture of sand and benzoic acid (soluble in hotwater) could be separated to produce pure benzoic acid.

A student dissolved 4 drops of an unknown compound in 1 mL of methylene chloride (dichloromethane) in a test tube. They added 5 drops of a 2% solution of bromine in dichloromethane dropwise and mixed the contents within the test tube gently. They observed the red-brown color discharges (turns colorless) until the last drop. What compound is most likely the unknown? ©GMU 2020 Oa. Methanol b. Cyclohexane c. n-Butyl Bromide O d. Hex-2-ene COLE QUESTION 6 A student placed 2 drops of an unknown sample in a test tube and added 2 mL of ethanol to the test tube while mixing gently. They added 2 drops of potassium permanganate reagent to the test tube and mixed the contents of the test tube gently. The initial color was a deep purple but then changed to a yellow color which precipitates as a brown solid. What compound is most likely the unknown? OGMU 2020 a. Cyclopentane O b. Cyclohexene c. 1-Pentyl Chloride d. 2-Propanol SOUL QUESTION 7 A student performed the Beilstein test within a chemical…
