In which of the following arrangements, the sequence is not strictly according  to the property written against it? [2008]
  • a)
    HF < HCl < HBr , HI : increasing acid strength
  • b)
    NH3 < PH3 < AsH3 <SbH3 : increasing basic strength
  • c)
    B < C < O < N : increasing first ionization enthalpy
  • d)
    CO2 < SiO2 < SnO2 < PbO2 : increasing oxidising power
Correct answer is option 'B'. Can you explain this answer?

(a,c) As we move from top to bottom in a group, the acidic strength of hydrides increases. Therefore, order of acidic strength of hydrides of VA and VII A group elements is

NH3 < PH3 < AsH3< SbH3
HF<HCl < HBr <HI
 
b) As we move from top to bottom in a group acidic nature (Ka) increases. Therefore, pKa decreases. Thus, order of pKa value of hydrides of VI A group  elements is
H2O > H2S >H2Se > H2Te

d) On moving from top to bottom, oxidising power of oxides increases. Thus, order of oxidising power of oxides of IVA group elements is 
CO2 < SiO< SnO2 < PbO2
