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.
