MCQ
Which of the following is non-conducting ?
- A$CoCl_3.6NH_3$
- B$CoCl_3.5NH_3$
- C$CoCl_3.4NH_3$
- ✓$CoCl_3.3NH_3$
✓
Answer
Correct option: D.
$CoCl_3.3NH_3$
d
As in octahedral complex, $\left[ CoCl _3 .3 NH _3\right]$ doesn't form any ion so it is nonconducting.
As in octahedral complex, $\left[ CoCl _3 .3 NH _3\right]$ doesn't form any ion so it is nonconducting.
But other complex give atleast one ion so they are conductor.
$CoCl _3 .4 NH _3$ gives two ion (one complex $+$ one chloride).
$CoCl _3 .5 NH _3$ gives three ion (one complex $+$ two chloride).
