Question

Bond angle for io3 BRo3 Cio3

Answer 1

Looking at the ClO3- Lewis structure we can see that there are three atoms attached to the central Chlorine (Cl) atom as well as a lone pair of electrons. ... The ClO3- bond angle will be about 109 degrees since it has a trigonal pyramidal molecular geometry.p

Answer 2

Bond Angle of $IO_{3}$ = 107°, $BrO_{3}$ = 104°, $CIO_{3}$ = 100°

• Bond Angle: Angle between the orbital electrons around the central atom.
• Bond angle decreases with decrease in electronegativity of the central atom. (According to VSEPR Theory)
• $CIO_{3}$ > $BrO_{3}$ > $IO_{3}$  
• After determining the bond angle, the structure of the molecule can be found using VSEPR (Valence Shell Electron  Pair Repulsion) theory.
• The theory is used to determine the number of pair electrons surrounding the central atoms, the geometrical arrangement of individual atoms.
