A) \[\text{0}\text{.01M N}{{\text{a}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}(\text{aq})\]
B) \[\text{0}\text{.01 M KN}{{\text{O}}_{\text{3}}}\text{ (aq)}\]
C) \[\text{0}\text{.015 M urea (aq)}\]
D) \[\text{0}\text{.015 M glucose (aq)}\]
Correct Answer: A
Solution :
Molecules having maximum number of ions will have maximum value of boiling point. In the given options, \[\text{0}\text{.01 M N}{{\text{a}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\]contains maximum number of ions. So, \[\text{0}\text{.01 M N}{{\text{a}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\]has highest boiling point.
