Question

Into a separatory funnel is poured 50 mL of CH_3CH_2Br (bromoethane), a water-insoluble compound with a density of 1.460 g/mL, and 50 mL of water. The funnel is stoppered and the mixture is shaken vigorously. After standing, two layers separate. Which substance is in which layer? Explain. The top layer is bromoethane and the bottom layer is water... The top layer is water and the bottom layer is bromoethane... ...because bromoethane has a higher molar mass than does water. ...because bromoethane is more dense than water. ...because water is added second. Into the same funnel is poured carefully 50 mL of hexane (density = 0.660 g/mL) so that the other two layers are not disturbed. The hexane forms a third layer. The funnel is stoppered and the mixture is shaken vigorously. After standing, two layers separate. Which compound(s) are in which layer?

Explanation / Answer

a) the top layer is water and bottom layer is bromo ethane because bromo ethane has more density than water in separating funnel, higher density compound is comes in bottom

b)In the top layer, contains haxane and bromo ethane because hexane and bromo ethane both are organic substance dissolved in each other. In bottom layer contain only water due to bromo ethane and hexane not soluble in water.
