Which is not obtained when metal carbides react with $H_2O$ ?
$A{l_4}{C_3} + {H_2}O \longrightarrow CH \equiv CH$
$CaC_2 + H_2O \longrightarrow CH \equiv CH$
$Mg_4C_3 + H_2O \longrightarrow C{H_3}C \equiv CH$
$Be_2C + H_2O \longrightarrow CH_4$
$AlC{l_3}$ is
Which is true about $H_3BO_3$
Draw structure of $Al_2Cl_6$ and give uses of $AlCl_3$.
$AlCl_3$ on hydrolysis gives:
Alumina is
