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

$\displaystyle \mathrm{H}_2 \mathrm{O}<\mathrm{H}_2 \mathrm{~S}$ : Increasing $\displaystyle \mathrm{pK}_{\mathrm{a}}$ $\displaystyle <\mathrm{H}_2 \mathrm{Se}<\mathrm{H}_2 \mathrm{Te}$ values

$\displaystyle \mathrm{NH}_3<\mathrm{PH}_3 \quad: \quad$ Increasing $\displaystyle <\mathrm{AsH}_3<\mathrm{SbH}_3 \quad$ acidic character
