NCERT Exercise 4.36 - Chemical Bonding and Molecular Structure
Question: Compare stability and magnetic properties of O2+, O2-, and O2^2-.
Answer: Bond orders: O2+ = 2.5, O2- = 1.5, O2^2- = 1. Thus stability: O2+ > O2- > O2^2-. O2+ and O2- are paramagnetic (one unpaired electron); O2^2- is diamagnetic.
