Problem: When windshields are treated with Rain-X, water quickly beads up and runs off rather than sticking more tightly to the glass. Which of the following is true?(a) From the point of view of the water molecules, the cohesive forces are stronger than the adhesive forces.(b) The compounds in Rain-X most likely have significant non-polar regions.(c) The compounds in Rain-X are most likely soluble in water.(d) Statements (a), (b), and (c) are all true.(e) Only statements (a) and (b) are true.

We’re being asked to determine which of given statements is/are true about Ran-X and water if water quickly beads up and runs off rather than sticking more tightly to the glass when windshields are treated with Rain-X.


Recall that water (H2O)is a polar molecule that exhibits hydrogen bonding.


Looking at each statement given:

(a) From the point of view of the water molecules, the cohesive forces are stronger than the adhesive forces.
