    What is not produced when sulphur reacts with boiling\[NaOH\]?

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

    B) \[S{{O}_{2}}\]

    C) \[N{{a}_{2}}{{S}_{2}}{{O}_{3}}\]               

    D) \[{{H}_{2}}O\]

    Correct Answer: B

    Solution :

                     \[4S+6NaOH\xrightarrow{Boil}2N{{a}_{2}}S+N{{a}_{2}}{{S}_{2}}{{O}_{3}}+3{{H}_{2}}O\] Thus,\[S{{O}_{2}}\]is not produced when sulphur reacts with boiling\[NaOH\].
