Aluminium chloride in acidified aqueous solution gives a complex ion ' $X^{\prime}$. The hybridisation of central atom in $X$ is
$s p^3$
$s p^2 d$
$d^2 s p^3$
$s p^3 d^2$
Solution
If aluminium chloride in acidified aqueous solution forms a complex $\left[\mathrm{Al}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}$ that is hexa aquaaluminium (III) ion, and $\mathrm{Al}$ is in $s p^3 d^2$ hybridisation.
$
\mathrm{AlCl}_3+6 \mathrm{H}_2 \mathrm{O} \longrightarrow\left[\mathrm{Al}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}+3 \mathrm{Cl}^{-}
$
Electronic configuration of $\mathrm{Al}^{3+}$
