(a)

Interpretation Introduction

Interpretation:

The compound ethylene glycol is either dissolves in gasoline or not has to be predicted.

Concept introduction:

Like dissolves like principle: ‘Like dissolves like’ principle says 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.

Polar molecule: Polar molecules have large dipole moments.

Non-Polar molecules: Non-polar molecules have bonded atoms with similar electronegativity results to have zero dipole moments.

Solubility is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.
