Answer:
See explanation below
Explanation:
First, you need to know the density of each compound in order to know this.
The density of 1-chlorobutane is 0.88 g/mL,
The density of water is 1 g/mL
The density of sodium bicarbonate is 2.2 g/cm3.
therefore, the one that has a greater density will always go at the lower phase.
In this case, after the reflux, it will stay in the lower phase, basically because you don't have another solvent with a greater density than the butane.
After adding water, it will be in the upper phase, water has a greater density.
After adding bicarbonate, it will be in the upper phase too.
