What is ideal bond angle?
Bond angles also play a role on a molecule's structure. The angles between neighboring lines that form bonds are known as bond angles. It is possible to distinguish between linear, trigonal planar, tetrahedral, trigonal-bipyramidal, and octahedral structures using the bond angle. The ideal bond angles are those that show the highest angle at which repulsion would be minimized, supporting the VSEPR theory.
In essence, bond angles indicate that electrons dislike being close to one another. Negative ions are electrons. Negatives don't attract each other. Make a comparison now. A negative person is typically viewed as unpleasant or mean, and you don't want to interact with them.
