Question

In which of the following arrangements, the sequence is not strictly according to the property written against it?
(a) HF < HCl < HBr , HI : increasing acid strength
(b) NH₃ < PH₃ < AsH₃ (c) B < C < O < N : increasing first ionization enthalpy
(d) CO₂ < SiO₂ < SnO₂ < PbO₂ : increasing oxidising power

Answer 1

CO₂ < SiO₂ < SnO₂ < PbO₂ : increasing oxidising power is the correct answer
