Chapter 13.2, Problem 13.2.2SR

Interpretation Introduction

Interpretation:

The compounds that are more soluble in water and can form a hydrogen bond between solute and solvent from the given compounds are to be determined.

Concept introduction:

‘Like dissolves like’ principle said that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non-polar compound should be more soluble in non-polar solvent. Other hand, compounds with similar intermolecular force capability to soluble in one another because solute-solvent interactions are similar signification to the solute-solute interaction.

‘The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:

• Hydrogen bonding
• London dispersion force
• Ion – dipole force
• Dipole – Dipole force

Ion – dipole force is a strong intermolecular force as it contains both ionic and polar bonds.

Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.

Dipole – Dipole: This force takes place between two polar compounds.

London dispersion force: This force is present in all compounds and is a weak force.

To determine: The compounds that are more soluble in water and can form a hydrogen bond between solute and solvent from the given compounds.
