Which compound will not give positive chromyl chloride test?
Correct answer: D. C4H9NH4+Cl-
- A. CuCl2
- B. ZnCl2
- C. HgCl2
- D. C4H9NH4+Cl-
Explanation
d) C4H9NH4+Cl- (Tetra-n-butylammonium chloride):Tetra-n-butylammonium chloride is a quaternary ammonium salt and does not contain a metal ion. Therefore, it will not react with chromyl chloride to produce the characteristic color. Hence, this compound will not give a positive chromyl chloride test.
