Butyne and 2-Butyne can be identified by using which of the following reagents?
Correct answer: C. NaNH2
- A. O2
- B. Br2
- C. NaNH2
- D. HCl
Explanation
The correct answer is Option C: NaNH2. 1-Butyne and 2-butyne can be differentiated using NaNH2 due to the reactivity of terminal hydrogen. Option A and Option B do not provide specific methods for distinguishing between the two compounds, while Option D is not relevant for this identification process.
