Em tham khảo nha :
\(\begin{array}{l}
{C_2}{H_2}\\
{C_2}{H_2} + 2{H_2} \xrightarrow{t^0,xt:Ni} {C_2}{H_6}\\
{C_2}{H_2} + {H_2}O \xrightarrow{t^0,xt,H^0} C{H_3}CHO\\
2AgN{O_3} + {C_2}{H_2} + 2N{H_3} \xrightarrow{t^0,xt} 2N{H_4}N{O_3} + A{g_2}{C_2}\\
\Pr opin:\\
{C_3}{H_4} + 2{H_2} \xrightarrow{t^0,xt:Ni} {C_3}{H_8}\\
{C_3}{H_4} + AgN{O_3} + N{H_3} \xrightarrow{t^0,xt} N{H_4}N{O_3} + AgC \equiv C - C{H_3}\\
But - 1 - in\\
{C_4}{H_6} + 2{H_2} \xrightarrow{t^0,xt:Ni} {C_4}{H_{10}}\\
C{H_3} - C{H_2} - C \equiv CH + AgN{O_3} + N{H_3} \xrightarrow{t^0,xt} C{H_3} - C{H_2} - C \equiv CAg + N{H_4}N{O_3}\\
But - 2 - in\\
{C_4}{H_6} + 2{H_2} \xrightarrow{t^0,xt:Ni} {C_4}{H_{10}}\\
C{H_3} - C \equiv C - C{H_3} + AgN{O_3} + N{H_3} \xrightarrow{t^0,xt} C{H_3} - C \equiv C - C{H_2}Ag + N{H_4}N{O_3}
\end{array}\)
