How is molecular polarity related to solubility?

How is molecular polarity related to solubility? please give details

Expert Solution

Explaination:

Polar substances tend to dissolve in polar solvents, and nonpolar substances dissolve in nonpolar solvents.

When a solute dissolves in a solvent the individual particles of the solute separate from their neighbours and move between the spaces of the solvent particles.

The solvent particles collide with the solute particles and the intermolecular forces of attraction between solute and solvent particles "hold" the solute particles in the spaces.

There are three steps to the dissolving process:

The solvent particles must move apart to make room for solute particles. This process requires energy to overcome forces of attraction between solvent particles. This step is endothermic.

The solute particles must separate from their neighbours. This process also requires energy to overcome the forces of attraction between the solute particles. This step is endothermic.

When the solute particles move between the solvent particles, the intermolecular forces of attraction between solute and solvent take hold and the particles "snap" back and move closer. This process releases energy. This final step is exothermic.

The quick answer is that “Like dissolves like”.

1. Bond polarity and molecular shape determine molecular polarity, which is measured as a dipole moment. True or False? 2. Molecular shape and polarity can affect physical properties, such as boiling point, and they play a central role in biological function. True or False? 3. A molecule with polar bonds is not necessarily a polar molecule. When bond polarities cancel each other, the molecule is nonpolar; when they reinforce each other, the molecule is polar. True or False?

What does polarity mean in this context? Is it an electrical polarity or a molecular one?

An action potential can be propagated in either direction along the surface of an axon. The direction it follows under physiological conditions is determined by a consistent polarity at most synapses What does polarity mean in this context? Is it an electrical polarity or a molecular one?
