Question

Q. Which of the following statement is correct?
A \(\mathrm{F}_{2}\) oxidises \(\mathrm{H}_{2} \mathrm{O}\) to \(\mathrm{O}_{2}\) but \(\mathrm{Cl}_{2}\) does not.
B Fluoride is a good oxidizing agent.
c \(\mathrm{Cl}_{2}\) oxidises \(\mathrm{H}_{2} \mathrm{O}\) to \(\mathrm{O}_{2}\) but \(\mathrm{F}_{2}\) does not.
D \(\mathrm{Cl}_{2}\) is a stronger oxidizing agent than \(\mathrm{F}_{2}\).

Answer 1

Solution:
$$
\begin{aligned}
&2 \mathrm{~F}_{2(g)}+2 \mathrm{H}_{2} \mathrm{Ol} \rightarrow 4 \mathrm{H}_{(a q)}^{+}+4 \mathrm{~F}_{(a q)}^{-}+\mathrm{O}_{2(g)} \\
&X_{2(g)}+\mathrm{H}_{2} \mathrm{O}_{(l)} \rightarrow \mathrm{HX}_{(a q)}+\mathrm{HOX}_{(a q)} \\
&X=\mathrm{Cl}_{2} \text { or } \mathrm{Br}_{2}
\end{aligned}
$$
