    Metal oxides are basic i.e., form alkaline solutions when dissolved in water. Similarly, non-metal oxides are acidic while semi-metal oxides are amphoteric in nature. Most basic oxide among following is

    A)  \[N{{a}_{2}}O\]                      

    B)  \[S{{O}_{2}}\]

    C)  \[C{{O}_{2}}\]                       

    D)  \[A{{l}_{2}}{{O}_{3}}\]

    Correct Answer: A

    Solution :

    \[{{\operatorname{Na}}_{2}}O + {{H}_{2}}O \xrightarrow{{}}\,\,NaOH\] \[{{\operatorname{SO}}_{2}} + {{H}_{2}}O \xrightarrow{{}}\,\,{{H}_{2}}S{{O}_{3}}\] \[\operatorname{C}{{O}_{2}} + {{H}_{2}}O \xrightarrow{{}}\,\,{{H}_{2}}C{{O}_{3}}\] \[{{\operatorname{Al}}_{2}}{{O}_{3}} + {{H}_{2}}O \xrightarrow{{}}\,\,Al{{\left( OH \right)}_{3}}\] NaOH is the most basic among the above compound.
