A) \[N{{a}_{2}}O\]
B) \[MgO\]
C) \[A{{l}_{2}}{{O}_{3}}\]
D) \[Si{{O}_{2}}\]
Correct Answer: B
Solution :
Key Idea: The oxide having maximum heat of formation per oxygen atom (thus energy needed to break one M-O bond will be highest) will be most stable \[\therefore \] MgO is most stable oxide among \[N{{a}_{2}}O\], \[Si{{O}_{2}}A{{l}_{2}}{{O}_{3}}\] and \[MgO\]You need to login to perform this action.
