Aluminium chloride exists as a dimer, $Al_2Cl_6,$ in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives:
$Al^{3+} +3Cl^-$
$[Al(H_2 O)_6 ]^{3+} + 3Cl^-$
$[Al(OH)_6]^{3-} + 3HCl$
$Al_2O_3 + 6HCl$
Heating an aqueous solution of aluminium chloride to dryness will give:
The tendency of $BF_3, BCl_3$ and $BBr_3$ to behave as Lewis acid decreases in the sequence
Describe the shapes of $BF_3$ and $BH_4^-$. Assign the hybridisation of boron in these species.
The stability of $+ 1$ oxidation state among $Al,Ga, In$ and $Tl$ increases in the sequence
The incorrect stability order of $+3$ and $+1$ states of $13^{th}$ group elements (boron family) is
