The number of isomers possible for the octahedral complex \(\left[\mathrm{CoCl}_{2}(\mathrm{en})\left(\mathrm{NH}_{3}\right)_{2}\right]^{+}\)is
1 two
2 three
3 no isomer
4 four
Explanation:
Two geometrical isomers are possible i.e, cis and trans. Two optically active isomers are possible. So, total no. of isomers are '4'.

Assertion : The total number of isomers shown by \(\left[\mathrm{Co}(\mathrm{en})_{2} \mathrm{Cl}_{2}\right]^{+}\)complex ion is three. Reason : \(\left[\mathrm{Co}(\mathrm{en})_{2} \mathrm{Cl}_{2}\right]^{+}\)complex ion has an octahedral geometry.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The complex \(\left[\mathrm{Co}(\mathrm{en})_{2} \mathrm{Cl}_{2}\right]^{+}\)exists in both cis and trans isomers. Among these, only the cis-isomer, can exhibit optical activity. Thus, three isomers are shown by the compound. Compounds with a coordination number of 6 typically adopt an octahedral geometry. So the option (2) is correct.

Give the total number of possible isomers of \({\mathrm{\left[\mathrm{CoCl}_{2}(\mathrm{CN})\left(\mathrm{NH}_{3}\right) \mathrm{en}\right]}}\).
1 2
2 4
3 8
4 6
Explanation:
There are four geometrical isomers: two isomers of cis-dichloro and two isomers of trans-dichloro. All the two isomers cis-isomers are ptically active.Hence, there are six isomers.
