- A \(3,3,6\)
- B \(3,4,8\)
- C \(4,4,8\)
- D \(3,4,6\)
Answer & Solution
Correct Answer
(B) \(3,4,8\)
Step-by-step Solution
Detailed explanation
\({ Structure of } \mathrm{Al}_2 \mathrm{Cl}_6 \text { is }\) Therefore, (i) Oxidation state \((x)\) of 'Al' in \(\mathrm{Al}_2 \mathrm{Cl}\) : \(=2 x-6=0 \text { or } x=\{+\rangle\) (ii) Coordination number of \(\mathrm{Al}\) in \(\mathrm{Al}_2 \mathrm{Cl}_5\) is four (4), it…
