Why is 1-hexanol insoluble in water?

Answer 1

Despite the fact that 1-hexanol has a polar hydroxyl group (OH), it remains insoluble in water because of the rather large non-polar 6 carbon chain. So, overall, this compound is much more non-polar than it is polar.

Answer 2

1-hexanol is insoluble in water because it is a nonpolar molecule, whereas water is a polar molecule. The difference in polarity between the two substances prevents them from effectively mixing or dissolving in each other. This is due to the "like dissolves like" principle in chemistry, where polar substances tend to dissolve in polar solvents, and nonpolar substances tend to dissolve in nonpolar solvents.

Answer 3

1-hexanol hasn't a polar molecule. But hexanol has some solubilty in water - 5,9 g/L at 20 oC.
