Question

In which of the following arrangements, the sequence is not strictly according to the property written against it?, H F H C l H B r H I : increasing acid strength, N H 3 P H 3 A s H 3 S b H 3 : increasing basic strength, B C O N : increasing first ionization enthalpy, C O 2 S i O 2 S n O 2 P b O 2 : increasing oxidising power

MARKS App · Accepted Answer

As the correct basic strength order is as follows N H 3 > P H 3 > A s H 3 > S b H 3 Rest all are correct here.
