| Assertion: The boiling points of alkyl halides decrease in the order : \[RI\text{ }>\text{ }RBr\text{ }>\text{ }RCl\text{ }>\text{ }RF\]. |
| Reason: The boiling points of alkyl chlorides, bromides and iodides are considerably higher than that of the hydrocarbon of comparable molecular mass. |
A) Assertion and reason both are correct and reason is correct explanation of assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct but reason is wrong statement.
D) Assertion is wrong but reason is correct statement.
Correct Answer: B
Solution :
Correct explanation : The boiling points of alkyi halides are directly proportional to van der Waals' forces of attraction which in turn, depend upon the molecular size.
