प्रश्न
Assertion: The boiling points of alkyl halides decrease in the order:
RI > RBr > RCl > RF
Reason: The boiling points of alkyl chlorides, bromides and iodides are considerably higher than that of the hydrocarbon of comparable molecular mass.

उत्तर
Assertion and reason both are correct statements but reason is not correct explanation of assertion.
Explanation:
The given sequence of boiling points is correct:
RI > RBr > RCl > RF
Thionyl chloride is best halogen carrier to convert alcohol to alkyl halide because it gives byproducts in gaseous state. Thus, we get pure alkyl halide in this reaction.
