Which one of the following reactions does NOT belong to "Lassaigne's test" ?
- A \(Na + C + N \underset{\Delta}{\rightarrow} NaCN\)
- B \(2 Na + S \underset{\Delta}{\rightarrow} Na _2 S\)
- C \(Na + X \xrightarrow[\Delta]{\longrightarrow}+ NaX\)
- D \(2 CuO + C \underset{\Delta}{\rightarrow} 2 Cu + CO _2\)
Answer & Solution
Correct Answer
(D) \(2 CuO + C \underset{\Delta}{\rightarrow} 2 Cu + CO _2\)
Step-by-step Solution
Detailed explanation
\(2 CuO + C \underset{\Delta}{\rightarrow} 2 Cu + CO _2\)
"Lassaigne's test" is used to detect Nitrogen, Halogen, Sulphur, Phosphorus.
\(4^{\text {th}}\) option is detection of carbon, it is not "Lassaigne's test".
