Solution

This question tests organic compound identification via chemical tests. Column-I shows structures, Column-II lists tests they give positive for.

Key concepts:

• Bromine water decolorization (P): Tests unsaturation (alkenes/alkynes).

• Iodoform test (Q): For methyl ketones (CH₃C=O) or alcohols oxidizable to them (e.g., CH₃CH(OH)-).

• Cerric ammonium nitrate (R): Red color indicates alcohols.

• Brady's test (S): Orange precipitate confirms aldehydes/ketones.

Final answer: Match structures based on functional groups present.
