A student dissolved 4 drops of an unknown compound in 1 mL of methylene chloride (dichloromethane) in a test tube. They added 5drops of a 2% solution of bromine in dichloromethane dropwise and mixed the contents within the test tube gently. They observed thered-brown color discharges (turns colorless) until the last drop. What compound is most likely the unknown? ©GMU 2020Oa. Methanolb. Cyclohexanec. n-Butyl BromideO d. Hex-2-eneCOLE QUESTION 6A 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. Theyadded 2 drops of potassium permanganate reagent to the test tube and mixed the contents of the test tube gently. The initial colorwas a deep purple but then changed to a yellow color which precipitates as a brown solid. What compound is most likely theunknown? OGMU 2020a. CyclopentaneO b. Cyclohexenec. 1-Pentyl Chlorided. 2-PropanolSOUL QUESTION 7A student performed the Beilstein test within a chemical fume hood by inserting a looped end of a copper wire into the hottest part ofa flame on a Bunsen burner so the copper loop glowed. Once it glowed, they removed the copper loop and allowed it to cool. Finally,they dipped the copper loop into a test tube containing the unknown liquid and quickly placed the wet loop into the tip of the flame.The student observed an intense green flash within the flame. What compound is most likely the unknown? CGMU 2020a. Cyclohexeneb. n-Butyl Alcoholc. sec-Butyl Alcohold. t-Pentyl Chloride
