Question

Give me some reaction in the support of acidic nature of ethyne

Answer 1

Ethyne (Acytylene)  is much less acidic than water or ethanol. So it reacts with very strong Bases.

C2 H2   reacts with sodium amide in liquid ammonia and forms sodium acetylide.

           Na  NH2   +  C2 H2    ---->     Na C2 H  + NH3

C2 H2 also reacts with ButyLithium to form Lithium Acetylide  (in tetra hydro furan at ver cold temperature)

C2 H2  +  Bu Li   -->   Li C2 H  +  Bu H

Hope it helps you
