Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

Calculate the total number of \( \sigma \) bonds, \( \pi \) bonds, and lone pairs of electrons respectively on the central atom in an \( \text{I}_3^- \) ion (which is isoelectronic with \( \text{XeF}_2 \), having an \( \text{AB}_2\text{E}_3 \) steric arrangement).

1. A
   \( 2, 0, 3 \)
2. B
   \( 2, 1, 2 \)
3. C
   \( 3, 0, 2 \)
4. D
   \( 2, 0, 2 \)
