Question
Which of the following has more acidic character?(a) $\mathrm{H}_{2} \mathrm{Se}$(b) $\mathrm{H}_{2} \mathrm{~S}$(c) $\mathrm{H}_{2} \mathrm{O}$(d) $\mathrm{H}_{2} \mathrm{Te}$
Step 1
This is because as we move down the group, the size of the central atom increases. This leads to a decrease in the bond strength of the H-X bond (where X is the central atom), making it easier to donate a proton (H+). Show more…
