Step 1: Understand what haloalkanes are. Haloalkanes are organic compounds that contain carbon, hydrogen, and halogen atoms (like iodine, bromine, chlorine, or fluorine).
Step 2: Know that solubility in water depends on polarity. Polar molecules tend to dissolve well in water, while non-polar molecules do not.
Step 3: Identify the haloalkanes being compared. In this case, we are looking at iodoethane and other haloalkanes.
Step 4: Recognize that iodoethane contains iodine, which is a large and non-polar atom.
Step 5: Understand that the presence of the large non-polar iodine atom makes iodoethane less polar overall.
Step 6: Conclude that because iodoethane is less polar, it is less soluble in water compared to other haloalkanes that have smaller or more polar halogen atoms.
