In which of the following arrangements the given sequence is not strict according to the property indicated against it?

A

`HF lt HCl lt HBr lt HI` : increasing acid strength

B

`H_(2)O lt H_(2)S lt H_(2)Se lt H_(2)Te` : increasing `pK_(a)` values

C

`NH_(3) lt PH_(3) lt AsH_(3) lt SbH_(3)` : increasing acidic character

D

`CO_(2) lt SiO_(2) lt SnO_(2) lt PbO_(2)` : increasing oxidising power

Text Solution

Verified by Experts

The correct Answer is:
B
Increasing `pK_(a)` values means decreasing acidity but the given sequence represents increasing acidity. Thus, option (b) is incorrect.
