Question

Aluminium chloride in acidified aqueous solution forms a complex ${}^{\prime }{A}^{\prime }$, in which hybridisation state of $Al$ is ${}^{\prime }{B}^{\prime }$. What are ${}^{\prime }{A}^{\prime }$ and ${}^{\prime }{B}^{\prime }$, respectively ?

• A. $[Al(H_{2}O{)}_6{]}^{3+},s{p}^3{d}^2$
• B. $[Al(H_{2}O{)}_4{]}^{3+},s{p}^3$
• C. $[Al(H_{2}O{)}_4{]}^{3+},ds{p}^2$
• D. $[Al(H_{2}O{)}_6{]}^{3+},d^{2}s{p}^3$
