Bond Angles: Definition and Chart - Chemistry Learner
The two lone pairs will repel the bond pairs further, thereby reducing the bond angle to 104.5°. The overall shape of the molecule is bent or angular. The following chart shows the ideal and observed bond angles for different molecular shapes when lone pairs are introduced into the basic shape [1-5] . See more
