Question

Which of the following represents correct acidity order Li2O, BeO and B2O3 ? (A) Li2O < BeO < B2O3 (B) B2O3 < BeO < Li2O (C) BeO < Li2O < B2O3 (D) BeO < B2O3 < Li2O

The chemical nature of oxides of elements changes across the period as Basic oxide → Amphoteric oxide → Acidic oxide Thus, the correct increasing order of acidity is Li 2 O < BeO < B 2 O 3

Q. Which of the following represents correct acidity order $L i_{2} O$ , $B e O$ and $B_{2} O_{3}$ ?

$L i_{2} O < B e O < B_{2} O_{3}$

$B_{2} O_{3} < B e O < L i_{2} O$

$B e O < L i_{2} O < B_{2} O_{3}$

$B e O < B_{2} O_{3} < L i_{2} O$

The chemical nature of oxides of elements changes across the period as Basic oxide $\to$ Amphoteric oxide $\to$ Acidic oxide

Thus, the correct increasing order of acidity is

$L i_{2} O < B e O < B_{2} O_{3}$
