NettetThe basic structure must be H-O-O-H, with two lone pairs on each oxygen. Any of the two oxygens is surrounded by four centres of negative charge (two pairs shared with each hydrogen, two lone pairs). Maximum repulsion is achieved with a tetrahedral arrangement (angle = 109.5°), but each lone pair reduces the angle by 2.5° approx.
