Question

In which of the following arrangements, the sequence is not strictly according to the property written against it ?

Options

A.CO2 < SiO2 < SnO2 < PbO2 : increasing oxidising power
B.HF< HCl < HBr < HI : increasing acid strength
C.NH3 < PH3 < AsH3 < SbH3 : increasing basic strength
D.B < C < O < N : increasing first ionization enthalpy.

Solution

Correct basic strength is NH3 > PH3 > AsH3 > BiH3
