The complex ion `[Co(NH_(3))_(6)]^(3+)` is formed by `sp^(3) d^(2)` hybridiration. Hence, the ion should posses

Options

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

Answer

A

Explanation

Since the hybridisation of central metal tin`[Co(NH_(3))_(6)]^(+)` complex ion is `sp^(3)d^(2)` and coordination number of `Co^(3+)` is 6. So its geometry is octahedral.
