Options
- A
- B
- C
- D
Correct answer
A.
Step-by-step solution
is used to distinguish between 1-butyne and 2-butyne.
\begin{aligned}
&\begin{array}{r}
\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CH} \stackrel{\mathrm{NaNH}_2}{\longrightarrow} \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CNa} \\
+\frac{1}{2} \mathrm{H}_2 \uparrow
\end{array}\\
&\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{C}-\mathrm{CH}_3 \stackrel{\mathrm{NaNH}_2}{\longrightarrow} \text{ No reaction }
\end{aligned}$$$
