Vedclass · Answer

(D) $1$. $CaC_2 + 2H_2O \rightarrow Ca(OH)_2 + C_2H_2$ (Acetylene). Acetylene is a terminal alkyne $(HC \equiv CH)$,which reacts with $AgNO_3 / NH_4OH$ (Tollens' reagent) to form a white precipitate of silver acetylide $(AgC \equiv CAg)$.$2$. $2CHCl_3 + 6Ag \xrightarrow{\Delta} HC \equiv CH + 6AgCl$. Acetylene is formed,which gives a white precipitate with $AgNO_3 / NH_4OH$.$3$. $Mg_2C_3 + 4H_2O \rightarrow 2Mg(OH)_2 + CH_3-C \equiv CH$ (Propyne). Propyne is a terminal alkyne,which reacts with $AgNO_3 / NH_4OH$ to form a white precipitate of silver propyne $(CH_3-C \equiv CAg)$.$4$. $Al_4C_3 + 12H_2O \rightarrow 4Al(OH)_3 + 3CH_4$ (Methane). Methane is an alkane and does not react with $AgNO_3 / NH_4OH$ to form a precipitate.Therefore,the reaction that does not give a white precipitate is $Al_4C_3 \xrightarrow{H_2O}$.

Which of the following reactions does not produce a product that gives a white precipitate with $AgNO_3 / NH_4OH$?
