To determine the hybridization of an atom, you can follow these steps:
1. Find the central atom: For ClO3-, the central atom is chlorine (Cl).
2. Calculate the total number of valence electrons: Chlorine is in Group 7A, so it has 7 valence electrons. Oxygen (O) is in Group 6A and has 6 valence electrons. Since there are 3 oxygen atoms in ClO3-, the total number of valence electrons would be 7 + (6 × 3) + 1 (from the -1 charge) = 24 electrons.
3. Determine the number of electron pairs: Each single bond and lone pair counts as one electron pair. In ClO3-, there are three oxygen atoms bonded to the central chlorine atom. Therefore, there are three single bonds and one lone pair. So, the total number of electron pairs is 3 + 1 = 4.
4. Determine the hybridization: For four electron pairs, the possible hybridization options are sp3, which corresponds to tetrahedral geometry.
Therefore, the hybridization of chlorine in ClO3- is sp3.
c) sp3 is the correct answer.
