Q.
The complex ion $[Co(NH_3)_6]^{3+}$ is formed by $sp^3d^2$ hybridisation. Hence, the ion should possess
AIPMTAIPMT 1990Chemical Bonding and Molecular Structure
Solution:
Since the hybridisation of central metal tin $[Co(NH_3)_6]^{3+}$ complex ion is $sp^3d^2$ and coordination number of $Co^{3+}$ is 6. So, its geometry is octahedral.
