H2S, NF3, and OF2 are three structures in which we can anticipate variations from the idealized bond angle, but CF4 will not, as it lacks a lone pair on the central atom.

The structures have a tetrahedral geometry, which produces a bond angle of 109.8 degrees. Any deviation is the result of central ion lone pair repulsions and x lone pair repulsions.

Thus, there was less attraction between the nitrogen structures, which causes the NF3 bond angle to be less. When it comes to NH3, nitrogen has a stronger electronegative charge than hydrogen. The repulsion between the nitrogen bond grew as a result of it drawing in additional electrons. Consequently, it raises NH3's bond angle relative to NF3's.

This is due to the fact that oxygen has a higher electronegative charge than the sulphur atom, which will cause it to draw more electrons to itself and increase bond pair-bond pair repulsion, which leads to a widening of the bond angle in H2O. H2O's bond angle is 104.5 degrees, while H2S's bond angle is 92.1 degrees.
