Cl is surrounded by 4 electron groups: 2 bonds and 2 lone pairs
Since there are 4 electron groups around silicon, the electron geometry is tetrahedral, whose ideal bond angle is 109.5˚.Recall that lone pairs compress the bond angle, causing a deviation from the ideal bond angle.
ClO2- ideal bond angle is 109.5˚.
