Question

The complex ion $[Co(NH_3)_6]^{3+}$ is formed by $sp^3d^2$ hybridisation. Hence, the ion should possess

• A. octahedral geometry
• B. tetrahedral geometry
• C. square planar geometry
• D. tetragonal geometry

Answer 1

Answer: (A)

octahedral geometry

Answer 2

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.
