Answer:
CH3CH2CH2CH2CH2I > CH3CH2CH2CH2I > CH3CH2CH2I > CH3CH2I
Explanation:
The magnitude of London dispersion forces increases with increasing molecular mass and chain length. This is as a result of increase in the surface area of the molecule.
Hence, boiling points of molecules increase with increase in magnitude of London dispersion forces. This is the reason behind the ordering of molecules in the answer above.
CH₃CH₂CH₂CH₂CH₂I > CH₃CH₂CH₂CH₂I > CH₃CH₂CH₂I > CH₃CH₂I
The magnitude of London dispersion forces increases with increasing molecular mass and chain length. If there is an increase in chain length, there will be an increase in the strength of electrostatic attractions between molecules. This is as a result of increase in the surface area of the molecule.
Thus, boiling points of molecules increase with increase in magnitude of London dispersion forces.
Therefore, the order for boiling point will be as follows:
CH₃CH₂CH₂CH₂CH₂I > CH₃CH₂CH₂CH₂I > CH₃CH₂CH₂I > CH₃CH₂I
