Which of the following represents the incorrect decreasing order of bond angles?
View answer and explanation
Correct option: D
IO3−>BrO3−>ClO3−\mathrm{IO}_3^{-} > \mathrm{BrO}_3^{-} > \mathrm{ClO}_3^{-}
Option D (IO3−>BrO3−>ClO3−\mathrm{IO}_3^{-} > \mathrm{BrO}_3^{-} > \mathrm{ClO}_3^{-}) is correct because the bond angle decreases down the group due to increasing size and decreasing electronegativity of the central atom, making the given order incorrect.
