Arrange each set of compounds in the order increasing boiling points. (I) bromobenzene, chlorobenzene, iodobenzene (II) n-pentyl chloride, iso-pentyl chloride, neopentyl chloride Explain with reaction.

Answer»

ling point of n-pentyl chloride is higher than its isomeric neopentyl chloride.The branching of the chain makes the molecule more compact and decreases its SURFACE area.This DECREASE the MAGNITUDE of the Van der Waal's forces of existing between the TWO and consequently the boiling point decreases.Explanation:
