On the surface of polar stratospheric clouds, hydrolysis of chlorine nitrate gives A and B while its reaction with HCl produces B and C. A, B and C are, respectively

HOCl,

\mathrm{HNO_3}

\mathrm{Cl_2}

\mathrm{Cl_2}

\mathrm{HNO_3}

, HOCl

\mathrm{HClO_2}

\mathrm{HNO_2}

, HOCl

HOCl,

\mathrm{HNO_2}

\mathrm{Cl_2O}

Answer and worked solution

Official answer: A

On polar stratospheric clouds. $\mathrm{ClONO_2+H_2O\rightarrow HOCl+HNO_3}$ and $\mathrm{ClONO_2+HCl\rightarrow Cl_2+HNO_3}$ .

So A = HOCl, B = $\mathrm{HNO_3}$ , C = $\mathrm{Cl_2}$ .

(A)
