Cl2O, Br2O, I2O have positive value of (free energy) indicating that
these oxides are stable
these oxides are unstable and changes to X2 and O2
these disproportionate into X– and XO–
these oxides can form interhalogen compounds
Cl2O, Br2O, I2O have positive value of (free energy) indicating that,these are unstable and easily decomposed to produce halogen and oxygen molecules
