The correct Answer is:
To determine the shapes of the ions \([ClF_4]^-\) and \([ClF_2]^-\), we need to analyze their molecular geometry based on the number of valence electrons and the hybridization of the central chlorine atom. ### Step 1: Determine the number of valence electrons for \([ClF_4]^-\) 1. **Chlorine (Cl)** has 7 valence electrons. 2. Each **Fluorine (F)** has 7 valence electrons, and there are 4 fluorine atoms contributing a total of \(4 \times 7 = 28\) electrons. 3. The negative charge on the ion adds 1 additional electron. **Total valence electrons = 7 + 28 + 1 = 36 electrons.**
