A. 2-Methyl-1-propanol is more soluble in water than is glycerol because 2-methyl-1-propanol has a smaller molecular mass.
B. Glycerol is more soluble in water than is 2-methyl-1-propanol because glycerol has a smaller molecular mass.
C. 2-Methyl-1-propanol is more soluble in water than is glycerol because 2-methyl-1-propanol forms fewer hydrogen bonds with water.
D. Glycerol is more soluble in water than is 2-methyl-1-propanol because glycerol can form multiple hydrogen bonds with water.
