• # 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) $NaF+{{O}_{2}}$

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. $2NaOH+2{{F}_{2}}\to 2NaF+O{{F}_{2}}+{{H}_{2}}O$
