A) \[{{\operatorname{CrO}}_{3}}\]
B) \[\operatorname{Cr}{{\operatorname{CI}}_{3}}\]
C) \[\operatorname{Cr}{{\operatorname{O}}_{3}}{{\operatorname{CI}}_{2}}\]
D) \[{{\operatorname{Cr}}_{2}}{{\operatorname{O}}_{3}}\]
Correct Answer: C
Solution :
\[{{K}_{2}}C{{r}_{2}}{{O}_{7}}+4NaCl+3{{H}_{2}}S{{O}_{4}}\xrightarrow[\begin{smallmatrix} \,\,\text{Chromyl}\,\text{chloride} \\ \,\,\,\,\,\,\text{(red}\,\text{vapours)} \end{smallmatrix}]{\Delta }\] \[2Cr{{O}_{2}}C{{l}_{2}}+{{K}_{2}}S{{O}_{4}}+2NaS{{O}_{4}}+3{{H}_{2}}O\]
