A) \[CrC{{l}_{3}}\]
B) \[CrOC{{l}_{2}}\]
C) \[Cr{{O}_{2}}C{{l}_{2}}\]
D) \[C{{r}_{2}}{{O}_{3}}\]
Correct Answer: C
Solution :
\[NaCl+{{H}_{2}}S{{O}_{4}}+{{K}_{2}}C{{r}_{2}}{{O}_{7}}\,\to \]\[\underset{\text{Chromyl chloride}}{\mathop{Cr{{O}_{2}}C{{l}_{2}}+}}\,{{K}_{2}}S{{O}_{4}}+N{{a}_{2}}S{{O}_{4}}\]
