In which of the following arrangements, the sequence is not strictly according to the property written against it?
(AIEEE 2009)
  • a)
    CO2 < SiO2 < SnO2 < PbO2
    increasing oxidising power
  • b)
    HF < HCI < HBr < HI
    increasing acidic strength
  • c)
    NH3 > PH3 < AsH3 < SbH3
    increasing basic strength
  • d)
    B < C < O < N
    increasing first ionisation enthalpy
Correct answer is option 'C'. Can you explain this answer?

The correct increasing basic strength
SbH3 < AsH3 < PH3 < NH3
NH3 is most basic because of its small size, the electron density of electron pair is concentrated over small region.
As the size increases, the electron density gets diffused over a large surface area and hence, the ability to donate the electron pair (basicity) decreases. Hence, basic strength decreases down the group.
