Vedclass · Answer

(D) Pyridinium chlorochromate $(PCC)$ is formed by the reaction of pyridine with chlorochromic acid,which is obtained by dissolving chromium trioxide $(CrO_3)$ in aqueous $HCl$.The chemical formula of pyridine is $C_5H_5N$.When pyridine is protonated,it forms the pyridinium cation,$C_5H_5NH^{\oplus}$.The chlorochromate anion is $CrO_3Cl^{\ominus}$.Therefore,the structure of $PCC$ is $C_5H_5NH^{\oplus} CrO_3Cl^{\ominus}$.

The structure of $PCC$ is
