Question

The only molecule which can oxidize $H_{2}O$ to $O_2$ is:

• A. $N_2$
  
• B. $C{l}_2$
  
• C. $F_2$
• D. $Ne$

Answer 1

Answer: (C)

$F_2$

$F_2$ is the most electronegative element and $O_2$ is the second most electronegative element.
Hence, the only element which can oxidize $H_{2}O$ to $O_2$ is $F_2$.
