JEE MAIN - Chemistry (2025 - 23rd January Morning Shift - No. 9)
The incorrect statement among the following is
$\mathrm{PH}_3$ shows lower proton affinity than $\mathrm{NH}_3$.
$\mathrm{SO}_2$ can act as an oxidizing agent, but not as a reducing agent.
$\mathrm{NO}_2$ can dimerise easily.
$\mathrm{PF}_3$ exists but $\mathrm{NF}_5$ does not.
Explanation
$\mathrm{SO}_2$ can oxidise as well as reduce.
Hence it can act as both oxidising and reducing agent.
