How bond angles are determined

Web14 de fev. de 2024 · The bond angle decreases from the ideal 120° to approximately 119 or 118°. As a general rule of thumb, for each X replaced by a lone pair (E), the bond angle gets reduced by 2°. So, you need to subtract 2° from the ideal bond angle to obtain the bond angle for a specific shape.
