For example, CO2, with the Lewis structure shown below, has two electron groups (two double bonds) around the central atom. However, taking into account the size of the chlorines vs. the hydrogen, since the chlorines are larger, the ClCCl bond angle will be slightly more than 109.5 degrees, and the HCCl bond angle will then be slightly smaller.
