Vedclass · Answer

(D) $O_3$ and $SO_2$ both have a bent (angular) shape,so this statement is incorrect.$(B)$ The molecular formula of pyrosulphuric acid (oleum) is $H_2S_2O_7$,not $H_2S_2O_8$. Thus,this statement is incorrect.$(C)$ In the presence of moisture,$SO_2$ acts as a reducing agent,not an oxidising agent,as it gets oxidised to $H_2SO_4$ or $SO_3$. The reaction is: $SO_2 + 2H_2O \longrightarrow SO_4^{2-} + 4H^+ + 2e^-$.$(D)$ $V_2O_5$ acts as a catalyst in the contact process for the oxidation of $SO_2$ to $SO_3$. The reaction is: $2SO_2 + O_2 \xrightarrow{V_2O_5} 2SO_3$. This statement is correct.
