JEE Main Chemistry question

Statement 1: The boiling point of 0.1 M urea solution is less than that of 0.1 M KCl solution. Statement 2: Elevation of boiling point is directly proportional to the number of species present in the solution.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

KCl dissociates into and , doubling the number of particles compared to undissociated urea at the same molar concentration. Since boiling point elevation is directly proportional to the
