Q: Which of the following haloalkanes is expected to have the highest boiling point?

Solution: Iodoethane has the highest boiling point due to the larger size and polarizability of iodine.

Steps: 6

Step 1: Understand that haloalkanes are compounds that contain carbon, hydrogen, and halogen atoms (like iodine, bromine, chlorine).
Step 2: Know that boiling point is affected by the size and weight of the molecules. Larger molecules usually have higher boiling points.
Step 3: Identify the haloalkanes in the question. For example, iodoethane (C2H5I) contains iodine, which is larger than other halogens like bromine or chlorine.
Step 4: Recognize that iodine is more polarizable than smaller halogens. This means it can create stronger temporary dipoles, leading to stronger intermolecular forces.
Step 5: Compare the size and polarizability of the halogens in the haloalkanes. Iodine is the largest and most polarizable.
Step 6: Conclude that iodoethane, which contains iodine, will have the highest boiling point among the options given.
