Frequent question: Which substance has the stronger intermolecular attraction water or glycerol?

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.

Which substance has the stronger intermolecular attraction glycerol?

Hydrogen bonding is the predominant force for both molecules. Glycerol has three times as many O-H groups and many more H-bonding interactions than 1-propanol, so it experiences stronger intermolecular forces and greater viscosity. (Both molecules have the same carbon-chain length, so dispersion forces are similar.)

Which best compares the particles of the substance when it is in Region 1 with the particles of the substance when it is in Region 3 quizlet?

Which best compares the particles of the substance when it is in region 1 with the particles of the substance when it is in region 3? The particles are more orderly in region 1.

Which statement best explains why heating a liquid affects its viscosity quizlet?

Which statement best explains why heating a liquid affects its viscosity? The molecules move faster at higher temperatures and overcome attractions more easily.

Which substance has the stronger intermolecular attraction?

Strong intermolecular forces help hold the substance together, while weaker ones do not hold the molecules in the substance together as much. Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.

Which has stronger intermolecular forces liquid water or water vapor?

Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor pressure. Water has very strong intermolecular forces, hence the low vapor pressure, but it’s even lower compared to larger molecules with low vapor pressures.

Which factor best contributes to this property of water?

Which factor best contributes to this property of water? Water is made up of ionic bonds. Water has weak intermolecular forces.

Which description best characterizes the motion of particles in a solid?

Particles in the plasma move randomly, but particles in a solid vibrate in one place.

Which statement best describes the compressibility of a gas?

Terms in this set (10) Which statement best describes the compressibility of a gas? Increasing the temperature of a gas increases the pressure. Which step will decrease the pressure of a gas inside a closed cubical container?

Which statement best explains why heating a liquid affects its viscosity the molecules move faster at higher temperatures and overcome?

Which statement best explains why heating a liquid affects its viscosity? The molecules move faster at higher temperatures and overcome attractions more easily. The molecules move faster at higher temperatures, and the attractions between them increase.

Which molecules would most likely cause a liquid to have the highest viscosity?

Compounds with strong intermolecular forces the higher the greatest viscosity. This is because they require more energy to be able to break the bonds during the phase transition.

Which statement best describe viscosity?

Viscosity is a measure of a fluid’s resistance to flow.

It describes the internal friction of a moving fluid.

What is the strongest intermolecular force in water?

Since water has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces. The hydrogen bonds are the strongest force, but the other types of intermolecular attraction are still present.

What is the weakest intermolecular force of attraction?

The dispersion force is the weakest of all IMFs and the force is easily broken. However, the dispersion force can become very strong in a long molecule, even if the molecule is nonpolar.
