Question: In which one of the following arrangements the given sequence is not strictly according to the properties indicted against it?#

A) $\mathrm{CO}_2<\mathrm{SiO}_2<\mathrm{SnO}_2<\mathrm{PbO}_2$ : Increasing oxidizing order

B) $\mathrm{HF}<\mathrm{HCl}<\mathrm{HBr}<\mathrm{HI}$ : Increasing acidic strength

C) $\mathrm{H}_2 \mathrm{O}<\mathrm{H}_2 \mathrm{~S}<\mathrm{H}_2 \mathrm{Se}<\mathrm{H}2 \mathrm{Te}$ : Increasing $\mathrm{pK}{\mathrm{a}}$ values

D) $\mathrm{NH}_3<\mathrm{PH}_3<\mathrm{AsH}_3<\mathrm{SbH}_3$ : Increasing acidic character

Answer: $\mathrm{H}_2 \mathrm{O}<\mathrm{H}_2 \mathrm{~S}<\mathrm{H}_2 \mathrm{Se}<\mathrm{H}2 \mathrm{Te}$ : Increasing $\mathrm{pK}{\mathrm{a}}$ values#
