Two statements 'A' and 'R' are given below Select your answers to these items using the codes given below:
Assertion(A) : The complex ion `cis-[Co(en)_(2)Cl_(2)]^(+)` is optically active
Reason (R) : It is an octahedral complex

Assertion : The complex ion trans- [Co(en)_2Cl_2]^+ is optically active. Reason: It is an octahedral complex.

The complex ion [Co(en)_2Cl_2]^(+) exhibits

Two statements 'A' and 'R' are given below Select your answers to these items using the codes given below: Assertio (A) : Among the cobalt (III) complexes [Co(NH_(3))_(6)]^(3+) is a diamagnetic but [CoF_(6)]^(3-) is paramagnetic. Reason (R) : Hybridisation of [Co(NH_(3))_(6)]^(3+) is sp^(3)d^(2) where as hybridisation of Co in [CoF_(6)]^(3-) is d^(2)sp^(3) .

The EAN of cobalt in the complex ion [Co(en)_(2)Cl_(2)]^(+) is
