Question: Which haloalkane has the highest boiling point?
Options:
CH3Cl
C2H5Br
C3H7Cl
C4H9I
Correct Answer: C4H9I
Solution:
C4H9I has the highest boiling point due to the larger molecular size and stronger van der Waals forces.

Questions & Step-by-Step Solutions
Which haloalkane has the highest boiling point?
Step 1: Understand what haloalkanes are. Haloalkanes are organic compounds that contain carbon, hydrogen, and halogen atoms (like iodine, bromine, chlorine).
Step 2: Know that boiling point is affected by molecular size and intermolecular forces. Larger molecules usually have higher boiling points because they have stronger forces holding them together.
Step 3: Identify the haloalkanes being compared. In this case, we are looking at C4H9I (which is an iodide) and possibly other haloalkanes.
Step 4: Compare the molecular sizes of the haloalkanes. C4H9I has a larger molecular size because it contains iodine, which is heavier than other halogens like chlorine or bromine.
Step 5: Understand that iodine creates stronger van der Waals forces due to its larger size. This means that C4H9I will have stronger attractions between its molecules.
Step 6: Conclude that because of its larger size and stronger forces, C4H9I has the highest boiling point among the haloalkanes being considered.
