Glycerol boils at a higher temperature than water. What does this indicate about the attractive forces of glycerol? They are nonexistent.
They are the same as those in water.
They are stronger than those in water.
They are weaker than those in water.

They are stronger than those in water.

Explanation:

The attractive force between the particles of glycerol is stronger than that of water, so more heat energy is required to overcome this force and change it into gaseous form, that's why it boils at a higher temperature than water.

i need mutiple choices

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
