Which one of the following correctly represents the order of stability of oxides, X 2 O ; ( X = halogen ) ?

Options

ACl > I > Br
BBr > Cl > I
CI > Cl > Br
DBr > I > Cl

Correct answer

C. I > Cl > Br

Step-by-step solution

lodine oxygen bond is stable due to the greater polarity of bond and stability of chlorine oxygen bond is due to multiple bond formation with orbital of chlorine atom. Now, Br is not having both characteristics. So, the stability order of oxide is given as I > Cl > Br .
