C Cl_(4) gt CHCl_(3) gt CH_(2) Cl_(2) gt CH_(3) Cl is the decreasing order of boiling point in haloalkanes . Give reason .

Answer»

Solution : The boiling point of chloro, bromo and iodoalkanes INCREASES with INCREASE in the number of halogen ATOMS.
So the correct DECREASING order of boiling point of haloalkanes is:
`C Cl_(4) gt CHCl_(3) gt CH_(2) Cl_(2) gt CH_(3) CL` .
