Which is not obtained when metal carbides react with $H_2O$ ?
A
$A{l_4}{C_3} + {H_2}O \longrightarrow CH \equiv CH$
B
$CaC_2 + H_2O \longrightarrow CH \equiv CH$
C
$Mg_4C_3 + H_2O \longrightarrow C{H_3}C \equiv CH$
D
$Be_2C + H_2O \longrightarrow CH_4$
Solution
$\mathrm{Al}_{4} \mathrm{C}_{3}+\mathrm{H}_{2} \mathrm{O} \rightarrow 4 \mathrm{Al}(\mathrm{OH})_{3}+\mathrm{CH}_{4}$
Thus alkane is formed instead of acetylene.
