Answer is Option-3:
C₆H₁₄ (Hexane) and H₂O are immiscible.

Explanation:
Hexane is a chain of six carbon atoms attached to each other in straight chain and hydrogen atoms. All the bonds in this compound are non-polar. Hexane molecules interact with each other through London Dispersion Forces.
While, Water molecules are polar in nature, due to electronegativity difference between Oxygen and Hydrogen atoms the Hydrogen atom is partially positive and Oxygen atom is partially negative. And water molecles interact with each other through hydrogen bonding.

Result:
As we know LIKE DISSOLVES LIKE, so both Hexane and water are different from each other, so when mixed together thay fail to develop interactions with each other, Hence immiscible in each other.

Answer from: Quest

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
