A) \[MgO\]
B) \[CaO\]
C) \[N{{a}_{2}}O\]
D) \[A{{l}_{2}}{{O}_{3}}\]
Correct Answer: D
Solution :
Na, Mg and Ca are highly reactive metals and their oxides are strongly basic whereas \[\text{A}{{\text{l}}_{\text{2}}}{{\text{O}}_{\text{3}}}\]is amphoteric. So among all these \[\text{A}{{\text{l}}_{\text{2}}}{{\text{O}}_{\text{3}}}\]is comparatively acidic.You need to login to perform this action.
