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 `MgCl_2` , (iv)`10^(-2)` M NaClA. (i) lt (ii) lt (iv) lt (iii)B. (ii) lt (i) = (iii) lt (iv)C. (ii) lt (i) lt (iii) lt (iv)D. (iv) lt (iii) lt (i) = (ii) |

Answer» Correct Answer - C For `{:(10^(-4) "M NaCl", "i=2"),(10^(-4) "M Urea", "i=1"), (10^(-3) M MgCl_2, "i=3"),(10^(-2) "M NaCl", "i=2"):}` More the value of I,C, more will be the elevation in boiling point hence increasing order of boiling point is `10^(-4)` M Urea lt `10^(-4)` M NaCl lt `10^(-3)` M `MgCl_2` lt `10^(-2)` M NaCl. |
