Question

Rank the compounds in each of the following groups in order of increasing acidity or basicity, as indicated, and explain the order you assign. (a) acidity: HCl, HBr, HI (b) basicity: $\mathrm{H}_{2} \mathrm{O}, \mathrm{OH}^{-}, \mathrm{H}^{-}, \mathrm{Cl}^{-}$ (c) basicity: $\operatorname{Mg}(\mathrm{OH})_{2}, \mathrm{Si}(\mathrm{OH})_{4}, \mathrm{ClO}_{3}(\mathrm{OH})$ (Hint: Formula could also be written as $\mathrm{HClO}_{4}$ -). (d) acidity: HF, $\mathrm{H}_{2} \mathrm{O}, \mathrm{NH}_{3}, \mathrm{CH}_{4}$

Step 1

- As we move down the halogen group from Cl to Br to I, the bond strength decreases, leading to an increase in acidity. - Therefore, the correct order of increasing acidity is: **HCl < HBr < HI** ** Show more…
