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

A

`HFltHClltHBrltHI`: increasing acidic strength

B

`H_(2)OltH_(2)SltH_(2)SeltH_(2)Te`: increasing `pK_(a)` values

C

`NH_(3)ltPH_(3)ltAsH_(3)ltSbH_(3)`: increasing acidic character

D

`CO_(2)ltSiO_(2)ltSnO_(2)ltPbO_(2)`: increasing oxidizing power.

Text Solution

Verified by Experts

The correct Answer is:
B
The acidic character fo hydride increases down the group, so `pK_(a)`, decreases
