Arrange each set of compounds in order of increasing boiling points. (i) Bromomethane, Bromoform, Chloromethane, Dibromomethane. (ii) 1-Chloropropane, Isopropyl chloride, 1-Chlorobutane.

Question

Philoid · Accepted Answer

The order of increasing boiling point is

i) Chloromethane (CH₃Cl)< Bromomethane (CH₃Br) < Dibromomethane (CH₂Br₂)< Bromoform (CHBr₃)

ii) Isopropyl chloride (C₃H₇Cl)< 1-Chloropropane (C₃H₇Cl) < 1-Chlorobutane(C₄H₉Cl)

Generally, boiling point increases with the molecular weight of the compound and decreases with the branching of the chain.
