$Ga < In < Al$

Vedclass · Answer

(A) The melting points of group $13$ elements are influenced by their metallic bonding and crystal structure. The melting points of group $13$ elements follow the order: $B > Al > Tl > In > Ga$. Gallium $(Ga)$ has an unusually low melting point of $303 \ K$ because it exists as $Ga_2$ molecules in the solid state,which are held by weak van der Waals forces. Therefore,the correct order for $Al$,$Ga$,and $In$ is $Ga < In < Al$.

The correct order of melting points of $Al$,$Ga$,$In$ is
