Given below are two statements :
Statement I: Aluminium upon reaction with NaOH forms $\left[\mathrm{Al}(\mathrm{OH})_6\right]^{3-}$ ion.
Statement II : The geometry of $\mathrm{ICl}_4^{-}, \mathrm{ClO}_3^{-}$and $\mathrm{IBr}_2^{-}$is square planar, pyramidal and linear respectively.
In the light of the above statements, choose the correct answer from the options given below :
Select the correct option:
A
Both Statement I and Statement II are true
B
Both Statement I and Statement II are false
C
Statement I is true but Statement II is false
D
Statement I is false but Statement II is true

Solution
Statement 1 :
$$
\mathrm{Al}+\mathrm{NaOH}(\text { excess }) \rightarrow \mathrm{Na}\left[\mathrm{Al}(\mathrm{OH})_4\right]+\mathrm{H}_2(\mathrm{~g})
$$
Statement II :
$\mathrm{ClO}_3^1$ is $\mathrm{sp}^3$ and pyramidal
$\mathrm{ICl}_4^{\ominus}$ is $\mathrm{sp}^3 \mathrm{~d}^2$ and square planar
$\mathrm{IBr}_2^{!}$is $\mathrm{sp}^3 \mathrm{~d}$ and linear.
