Options

  1. AAl(OH)3\mathrm{Al}(\mathrm{OH})_3
  2. BCr(OH)3\mathrm{Cr}(\mathrm{OH})_3
  3. CLa(OH)3\mathrm{La}(\mathrm{OH})_3
  4. DFe(OH)3\mathrm{Fe}(\mathrm{OH})_3

Correct answer

C. La(OH)3\mathrm{La}(\mathrm{OH})_3

Step-by-step solution

La(OH)3\mathrm{La}(\mathrm{OH})_3 is the most basic as it has the largest atomic size. Al(OH)3\mathrm{Al}(\mathrm{OH})_3 is amphoteric in nature.
