Show the order of acid strength for the following. Explain the reasons for your decisions.
odd SiH4, PH3, H2S, HCl
even NH3, PH3, AsH3, SbH3
odd SiH4, PH3, H2S, HCl
From weakest to strongest: SiH4 < PH3 < H2S < HCl
When going across the Periodic Table, acid strength increases with increasing electronegativity
even NH3, PH3, AsH3, SbH3
From weakest to strongest: NH3 < PH3 < AsH3 < SbH3
When going down the Periodic Table, acid strength increases with increasing atomic size
