1. Water and Ethyl alcohol (miscible) both involves H-bonding. 2. Water and Diethyl ether (immiscible) water involves H-bonding, while ether not. 3. Water and metylene chloride (immiscible) water involves H-bonding, while CH2CL2 not. 4. Hexane and methylene chloride (miscible) for question 4. this is because the forces which hold molecules of methylene chloride together and the forces which hold hexane together are similar. Both are fairly weak forces sometimes known as Van der Waals forces. Solution 1. Water and Ethyl alcohol (miscible) both involves H-bonding. 2.
