Match items of column I and II

• Analysis: Water ($$\text{H}_2\text{O}$$) and dichloromethane ($$\text{CH}_2\text{Cl}_2$$) are immiscible liquids that form two distinct layers due to their differing densities and polarities.
• Technique: They are separated using a separating funnel via Differential solvent extraction (or simple liquid-liquid extraction).
• Match: A $$\rightarrow$$ (ii)

• Analysis: The image shows two structurally distinct organic compounds (a ketone and a substituted phenol) with different polarities and adsorption tendencies.
• Technique: Stationary phases like silica gel absorb these components differently, making Column chromatography the ideal method to separate them.
• Match: B $$\rightarrow$$ (iii)

• Analysis: Kerosene is a mixture of liquid hydrocarbons, while naphthalene is a volatile solid compound. Alternatively, mixtures of liquids with sufficient differences in boiling points or components that can be fractionated are separated by distillation.
• Technique: Fractional Distillation is used here to separate them based on boiling point differences.
• Match: C $$\rightarrow$$ (iv)

• Analysis: Glucose ($$\text{C}_6\text{H}_{12}\text{O}_6$$) and sodium chloride ($$\text{NaCl}$$) have vastly different solubilities in hot versus cold solvents (like alcohol/water mixtures).
• Technique: They can be separated cleanly by Crystallization, where one component forms crystals out of the solution while the other remains dissolved.
• Match: D $$\rightarrow$$ (i)

Hence,
