In which of the following arrangements, the sequence is not strictly according to the property written against it ? (1) CO2 < SiO2 < SnO2 < PbO2: increasing oxidising power (2) HF < HCl < HBr < HI : increasing acid strength (3) NH3 < PH3 < AsH3 < SbH3 : increasing basic strength (4) B < C < O < N : increasing first ionization enthalpy
