Question

Statement 1 :Aluminium chloride in acidified aqueous solution forms octahedral $[Al(H_2O)^{3+}]$ ion.
Statement 2 : In $[Al(H_2O )_6]^{3+}$ complex ion, the $3d$ orbitals of $Al$ are involved and the hybridisation state of $Al$ is $sp^3d^2$

• A. If both Statement $1$ and Statement $2$ are true and the statement $2$ is the correct explanation of the statement $1$
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$
• C. If Statement $1$ is true but Statement $2$ is false
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (A)

Both are correct and Statement $2$ is the correct explanation of Assertion. In $[Al(H_2O ))6]^{3+}$, aluminium is in $+3$ oxidation state. So,
$[Al(H_2 O)_6]^{3+} $
