What is the Werner secondary valence in complex \([CoCl(NH_3)_5]^{2+}2Cl^-\) ?
- A 3
- B 2
- C 5
- D 6
Answer & Solution
Correct Answer
(D) 6
Step-by-step Solution
Detailed explanation
\( \text{Secondary valence} = \text{Coordination Number} \) \( \text{Coordination Number} = 1 \times (\text{Cl}) + 5 \times (\text{NH}_3) = 1 + 5 = 6 \)
