हिन्दीIn the reaction, \( \mathrm{H-C \equiv C-H} \xrightarrow[ii. \mathrm{CH}_{3}\mathrm{CH}_{2}\mathrm{Br}]{i. \mathrm{NaNH}_{2} / \text{liq. } \mathrm{NH}_{3}} \mathrm{X} \xrightarrow[ii. \mathrm{CH}_{3}\mathrm{CH}_{2}\mathrm{Br}]{i. \mathrm{NaNH}_{2} / \text{liq. } \mathrm{NH}_{3}} \mathrm{Y} \) X and Y are
Correct answer · Option 1
\( \mathrm{X = But-1-yne ; Y = Hex-3-yne} \)
Explanation
Acetylene reacts with \( \mathrm{NaNH}_{2} \) and \( \mathrm{CH}_{3}\mathrm{CH}_{2}\mathrm{Br} \) to give But-1-yne (X), which upon further alkylation gives Hex-3-yne (Y).
