Question

how will you distinguish between but-1-yne and But-2-yne?​

Answer 1

Answer ⤵️

tollens test will be given by terminal alkynes... this way they can be differentiated... if ppt is found the alkyne is But-1-yne if not then it is But-2-yne. Ago But-1-yne is terminal alkyne and but-2-yne is nonterminal alkyne.So but-1-yne reacts with Na to form H2 but but-2-yne does not react with Na.Not only that but-1-yne reacts with ammonical silver nitrate and cuprous chloride solution to form white and red colour precipitate respectively. But but-2-yne being a nonterminal alkyne does not involve in these reaction.But1yne react with sodium and release hydrogen gas. but2yne not react with sodium due to absence of acidic hydrogen.

Hope it helps ♥️♥️♥️
