The hybridisation of atom ' \(X\) ' with atomic number 27 in \(\left[X \mathrm{~F}_6\right]^{3-}\) is
- A \(d s p^2\)
- B \(d^2 s p^3\)
- C \(s p^3 d^2\)
- D \(s p^3\)
Answer & Solution
Correct Answer
(C) \(s p^3 d^2\)
Step-by-step Solution
Detailed explanation
The atomic number of Co is 27 and its valence shell electronic configuration is \(3 d^7 4 s^2\). Hence, \(X=\) Co atom and \(\left[\left(\mathrm{CoF}_6\right)^{3+}\right]\) complex have \(s p^3 d^2\) hybridisation and shape is octahedral.
