In whichof the following arrangements, the givensequence is not strict

1.	In whichof the following arrangements, the givensequence is not strictly according to the property indicatedagainst it ?
Answer» `HF lt HCl lt HBr lt HI` : increasing acidie strength `H_(2)O lt H_(2)S lt H_(2)Se lt H_(2)Te`: increasing`pK_(a)` values `NH_(3) lt PH_(3) lt AsH_(3) lt SbH_(3)` : increasing ACIDIC character `CO_(2) lt SiO_(2) lt SnO_(2) lt PbO_(2)` : increasing oxidising power Solution :Acidity increases or `pK_(a)`the `H-M`bond strengthdecreasesfrom O toTe. Thus, OPTION (b) is not correct.
