Question

1-butyne can be distinguished from 2-butyne by using amm. AgNO3 explain .. give the reaction

Answer 1

1 butyne  is terminal alkyne while 2-Butyne is not.
therefore only 1-Butyne gives reaction with amm. AgNO3

2CH₃CH₂C≡CH + 2AgNO₃ + 2NH₄OH ⇒ 2CH₃CH₂CCAg + 2NH₄NO₃ + H₂O

CH₃C≡CCH₃ + AgNO₃ + NH₄OH ⇒ NO REACTION

HOPE THIS HELPS

IF ANY DOUBT PLEASE ASK
