Acidic property

Vedclass · Answer

(D) Acetylene $(HC \equiv CH)$ contains terminal hydrogen atoms attached to $sp$-hybridized carbon atoms. Due to the high $s$-character $(50\%)$ in $sp$-hybridized carbon,the $C-H$ bond is polar,making the hydrogen atom acidic. When acetylene reacts with ammoniacal silver nitrate $(Tollens' 	ext{ reagent})$,it forms a white precipitate of silver acetylide $(Ag-C \equiv C-Ag)$. This reaction is a characteristic test for terminal alkynes and confirms their acidic nature.

Acetylene shows ........... in its reaction with silver nitrate.
