Q. Assertion : The boiling point of the compounds increases in the order: Isopropylchloride $<\, 1$ - Chloropropane $<\, 1 $ Chlorobutane.
Reason: Boiling point depends upon the molecular mass and surface area.

Haloalkanes and Haloarenes

Solution:

Branched-chain isomers have lower b.p. as van der Waals forces depend on surface area and molecular mass. So, the order of the boiling point of the given compounds is Isopropyl chloride $<1$-Chloropropane $<1$-Chlorobutane.
