The pair of amphoteric hydroxides is

Options

  1. ABe(OH)2,Al(OH)3\mathrm{Be}(\mathrm{OH})_2, \mathrm{Al}(\mathrm{OH})_3
  2. BAl(OH)3,LiOH\mathrm{Al}(\mathrm{OH})_3, \mathrm{LiOH}
  3. CB(OH)3,Be(OH)2\mathrm{B}(\mathrm{OH})_3, \quad \mathrm{Be}(\mathrm{OH})_2
  4. DBe(OH)2,Mg(OH)2\mathrm{Be}(\mathrm{OH})_2, \mathrm{Mg}(\mathrm{OH})_2

Correct answer

A. Be(OH)2,Al(OH)3\mathrm{Be}(\mathrm{OH})_2, \mathrm{Al}(\mathrm{OH})_3

Step-by-step solution

Al\mathrm{Al} and Be show similar properties due to their diagonal relationship.
