NEET Chemistry Colligative Properties MCQ Question
Arrange the following aqueous solutions in the order of their increasing boiling points. (i) 10⁻⁴ M NaCl (ii) 10⁻⁴ M Urea (iii) 10⁻³ M MgCl₂ (iv) 10⁻² M NaCl
(i) < (ii) < (iv) < (iii)
(ii) < (i) = (iii) < (iv)
(ii) < (i) < (iii) < (iv)
(iv) < (iii) < (ii) < (i)
Correct Answer
Detailed Explanation
Boiling point elevation is proportional to the concentration of ions. Urea has no ions, while NaCl and MgCl₂ dissociate into ions.
