ChemistryHaloalkanes and HaloarenesMHT CET 2024

Which of the following is correct decreasing order of boiling point of compounds?

Answer: (C)

Solution

Among haloalkanes boiling point rises with molecular mass and size (stronger van der Waals/dispersion forces and larger polarisability), which here increases with the number and size of halogen atoms: (M = 50.5, bp about C) < (M = 95, about C) <
