The correct order of boiling points of alkyl halides is

A
$R I > R B r > R F > R C I$
B
$R I > R C I > R B r > R F$
Correct answer
C
$R R I > R B r > R > R F$
D
$R F > R B r > R > R I$

Solution

The correct order of boiling point of alkyl halides is Rl > RBr > RF. This is because with increase in size and mass of halogen atom. The magnitude of van der Waals’ forces increases.

Hence, the correct answer is option: 'C'.
