  • question_answer With cold and dilute sodium hydroxide fluorine reacts to give   [MH CET 2004]

    A) \[NaF\] and \[O{{F}_{2}}\]

    B) \[NaF+{{O}_{3}}\]

    C) \[{{O}_{2}}\ \text{and}\ {{O}_{3}}\]

    D) \[NaF+{{O}_{2}}\]

    Correct Answer: A

    Solution :

    Fluorine is the most electronegative element. It does not form oxyfluoxides like other halogens. If reacts with NaOH to form sodium fluoride and oxygen fluoride. \[2NaOH+2{{F}_{2}}\to 2NaF+O{{F}_{2}}+{{H}_{2}}O\]
