Question

why is glycerol less soluble in water than ethanol.

Answer 1

it has 3 hydroxyl groups compared to ethanol's single hydroxyl group

Answer 2

so glycerol must be more soluble ryt??

Answer 3

it is probably because glycerol is a larger molecule than ethanol, and solubility decreases as the size of the molecule increases

Answer 4

any other reason???

Answer 5

Glycerol is less polar, being larger, and ethanol has hydrogen bonding interactions with H2O, which reduces the enthalpic cost of solvation.
