To compare the complexes \([CoF_4]^{2-}\), \([Cr(H_2O)_2(C_2O_4)_2]^{-}\), and \([Ni(CO)_4]\) with respect to their shape, magnetic behavior, and the hybrid orbitals involved, we will analyze each complex step by step. ### Step 1: Analyze \([CoF_4]^{2-}\) 1. **Oxidation State**: - Cobalt in \([CoF_4]^{2-}\) has an oxidation state of +2. - Calculation: Let the oxidation state of Co be \(x\). Since F is -1 and there are 4 F atoms, we have: \[ ...
