Question

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.

Options

  • Assertion and reason both are correct and reason is correct explanation of assertion.

  • Assertion and reason both are wrong statements.

  • Assertion is correct but reason is wrong statement.

  • Assertion is wrong but reason is correct statement.

  • Assertion and reason both are correct statements but reason is not correct explanation of assertion.

Solution

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.
