$Be_2C + 4H_2O 	o 2Be(OH)_2 + C_2H_6$

Vedclass · Answer

(D) The hydrolysis of metal carbides produces specific hydrocarbons based on the carbon unit present in the carbide:$1$. $Al_4C_3$ (methanide) yields $CH_4$ (methane): $Al_4C_3 + 12H_2O 	o 4Al(OH)_3 + 3CH_4$.$2$. $CaC_2$ (acetylide) yields $C_2H_2$ (acetylene): $CaC_2 + 2H_2O 	o Ca(OH)_2 + C_2H_2$.$3$. $Mg_2C_3$ (allylide) yields $CH_3C \equiv CH$ (propyne): $Mg_2C_3 + 4H_2O 	o 2Mg(OH)_2 + CH_3C \equiv CH$.$4$. $Be_2C$ (methanide) yields $CH_4$ (methane): $Be_2C + 4H_2O 	o 2Be(OH)_2 + CH_4$.Option $D$ is incorrect because $Be_2C$ produces methane,not ethane.
