Interpretation:
The reason for the miscibility of ethanol in water and the immiscibility of cyclohexane in water has to be given.
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
Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.

- Use molecular structures and noncovalent interactions to explain why dimethyl ether, (CH3)2O, is completely miscible in water, but dimethylsulfide, (CH3)2S, is only slightly water soluble.arrow_forwardWhen a small amount of pentane is in contact with a water droplet on top of a glass table, it forms a very thin film that covers the droplet and part of the table. Why does the pentane spread out and not form a droplet? Why does water form a droplet on glass (and not spread out)? Why do water and pentane not mix? How is the pentane able to "creep" up and across the water droplet to form a film? Please answer the questions by focusing on intermolecular forces.arrow_forwardWhich would you expect to be more soluble in water, cyclohexane or dioxane?arrow_forward
