A) \[L{{i}_{2}}O,N{{a}_{2}}{{O}_{2}}\] and\[K{{O}_{2}}\]
B) \[L{{i}_{2}}O,N{{a}_{2}}O\]and \[K{{O}_{2}}\]
C) \[Li{{O}_{2}},N{{a}_{2}}{{O}_{2}}\]and \[{{K}_{2}}O\]
D) \[L{{i}_{2}}{{O}_{2}},N{{a}_{2}}{{O}_{2}}\] and \[K{{O}_{2}}\]
Correct Answer: A
Solution :
The stability of the oxide of alkali metals depends upon the comprability of size of cation and anion. Therefore the main oxide of alkali metals formed on excess of air are as follows : Li \[L{{i}_{2}}O\] Na \[N{{a}_{2}}{{O}_{2}}\] K \[K{{O}_{2}}\] Rb \[Rb{{O}_{2}}\] Cs \[Cs{{O}_{2}}\]
