{\mathrm{H}_2}\mathrm{S}{\mathrm{O}_4}

gives

View answer and explanation

Correct option: A

\mathrm{Cr}{\mathrm{O}_2}\mathrm{C}{\mathrm{l}_2}

Option A (

\mathrm{Cr}{\mathrm{O}_2}\mathrm{C}{\mathrm{l}_2}

) is correct because the reaction of potassium dichromate with NaCl and concentrated sulfuric acid produces chromyl chloride.
