Vedclass · Answer

(B) $(I)$ $Ga_2O_3$ is an amphoteric oxide. This is a correct statement as it reacts with both acids and bases:Reaction with an acid: $Ga_2O_3 + 6 HCl \longrightarrow 2 GaCl_3 + 3 H_2O$Reaction with a base: $Ga_2O_3 + 2 NaOH \longrightarrow 2 NaGaO_2 + H_2O$$(II)$ The dimer of aluminium chloride $(Al_2Cl_6)$ has only two $Al-Cl-Al$ bridge bonds,not three. The structure consists of two $AlCl_4$ tetrahedra sharing a common edge.$(III)$ Boron is a very hard refractory solid with a high melting temperature $(2349 \ K)$,which is a correct statement.Therefore,statements $I$ and $III$ are correct. The correct option is $(b)$.

Identify the correct statements from the following :
$I$. $Ga_2O_3$ is an amphoteric oxide.
$II$. The dimer of aluminium chloride has three $Al-Cl-Al$ bridge bonds.
$III$. Boron is a very hard refractory solid of high melting temperature.
