Predict whether the following pairs of liquids would be miscible or immiscible: a. water and methyl alcohol b. hexane and benzene c. methylene chloride and benzene d. water and toluene e. cyclohexanone and water

a) water and methyl alcohol  

  Both are polar liquids, therefore, they are miscible.

b) Hexane and benzene

   Both the liquids are nonpolar hence they are miscible.

c) Methylene chloride and benzene

   Methylene chloride is polar in nature and benzene is nonpolar hence these liquid is immiscible in nature.

d) Water and toluene

   water is polar in nature and toluene is nonpolar hence immiscible.

e) Cyclohexanone and water

  Both are polar liquids, therefore, they are miscible.
