Vedclass · Answer

(D) The hydrolysis of carbides produces different hydrocarbons based on the carbon species present in the crystal lattice.$CaC_2$ contains the acetylide ion $(C_2^{2-})$ and yields ethyne $(C_2H_2)$.$Be_2C$ and $Al_4C_3$ contain the methanide ion $(C^{4-})$ and yield methane $(CH_4)$.$Mg_2C_3$ contains the allylide ion $(C_3^{4-})$ and yields propyne $(CH_3-C \equiv CH)$ upon hydrolysis.The reaction is: $Mg_2C_3 + 4H_2O 	o 2Mg(OH)_2 + CH_3-C \equiv CH$.

Which of the following carbides will give propyne on hydrolysis?
