Question

In the purification of cyclohexene, the purpose of extracting with saturated aqueous sodium chloride/adding calcium chloride is to

a) Increase the yield
b) Remove impurities
c) Enhance the color
d) Speed up the reaction

Answer 1

The purpose of extracting with saturated aqueous sodium chloride and adding calcium chloride in the purification of cyclohexene is to remove impurities.

Step-by-step explanation:

The purpose of extracting with saturated aqueous sodium chloride and adding calcium chloride in the purification of cyclohexene is to remove impurities.

When compounds are synthesized, contaminating materials can be mixed in with them. The process of recrystallization can be used to remove these impurities. Adding saturated aqueous sodium chloride and calcium chloride helps to separate the impurities from the desired product.
