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

Answer»

Assertion and reason both are correct and reason is correct explanaion of assertion.
Assertion and reason both are WRONG statements.
Assertion is correct but reason is wrong statement.
