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:
Aluminium trifluoride is insoluble in anhydrous $HF$ but dissolves on addition of $NaF$. Aluminium trifluoride precipitates out of the resulting solution when gaseous $BF $$_{3}$ is bubbled through. Give reasons.
Anhydrous $AlCl_3$ is formed in
The species, having bond angles of $120^o $ is
