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.
