Question
19. A student complened a very thorough extraction of an aqueus solution using dicthyl-ether (CH,CH-O-CHCHik After standing foer a while in a seperstory funnel two distinct lyrswere obscrved Which of the tollowiag is (ere) true? A) The organic solvenn (ether) is more dense than water B) The ceganic solvent (ether) s less dennse than wator C) Water the aqueous layer) is the upper layer D) None of the above 20. Dicyclopentadiene is the Diebs-Alder addition prodact of two melecules of 1.3 eyclopentadiene. The structure of dicyelopentadime is IC) 21 Write the equation foe the overall reaction of cyclopentadiene and maleic anhy dride Your answer should clearly show the endo and exo forms of the roduct. 22. Using Fisher Projection formulas draw the four stereoisomeric forms of 3-amino-2 butanol. Using R,S notations provide compiete stereochemical names for cach stereulsomer.Explanation / Answer
Q19
ethyl acetate has a density of 0.78 g/mL approx, therefore it is LESS dense than water
the water will be the bottom layer
therefore
choose B
