Which of the following statements are true? Give reason to support your answer. {a , b , c} and {1,2,3} are equivalent sets.

Which of the following species are hypervalent? (A) ClO_(4)^(-)" "(B)BF_(3) (C ) SO_(4)^(-2)" "(D)CO_(3)^(-2)

represents the distillation of mixture of liquid A and liquid B which gives both of pure liquid A and B . Represents the azeotropic mixture of HNO_(3) and H_(2)O which distillation gives an azeotropic mixture and either of pure liquid. We cannot separate both the pure liquid, i.e., H_(2)O and HNO_(3) . Which of the following statements is/are correct? i. HNO_(3) solution is not obeying the Raoult's law. ii. More the difference in vapour pressure of pure compounds forming a mixture, easier to separate them through distillation. iii. T_(2) is less than T_(1) because the liquid of composition Q is richer in more volatile component.
