Which of the following has the highest boiling point? A)CH₃CH₂CH₂CH₂CH₂Br B)CH₃CH₂CH₂CH₂CH₂I C)CH₃CH₂CH₂CH₂CH₃ D)CH₃CH₂CH₂CH₂CH₂F E)CH₃CH₂CH₂CH₂CH₂Cl

Question

Quizplus · Accepted Answer

The boiling point of a compound depends on the strength of intermolecular forces between its molecules. Among the given options, compound B, which is a mixture of the same molecule with both Chlorine and Iodine, has the highest boiling point due to the presence of strong London dispersion forces between its large and polarizable molecules. The other compounds have weaker intermolecular forces and hence lower boiling points.
