Vedclass · Answer

(B, C) . $SO_{2}$ is oxidized to $SO_{3}$ by $O_{3}$ in the atmosphere,so it acts as a sink. This statement is correct.$B$. $FGD$ (Flue Gas Desulfurization) is a process used to remove $SO_{2}$ from flue gases,not $NO_{2}$. This statement is incorrect.$C$. $NO$ is not easily removed by alkaline scrubbing because it is neutral. $NO_{2}$ can be removed by alkaline scrubbing. This statement is incorrect.$D$. The reaction $CCl_{4} + HF \xrightarrow{SbF_{5}} CF_{4} + HCl$ is a standard fluorination reaction using $SbF_{5}$ as a catalyst. This statement is correct.Therefore,statements $B$ and $C$ are incorrect.
