tetrahedral bond angle
The tetrahedral bond angle refers to the angle formed between two bonds in a molecule that has a tetrahedral shape, where a central atom is surrounded by four other atoms. In this arrangement, the atoms are positioned at the corners of a tetrahedron, creating a bond angle of approximately 109.5 degrees. This geometry minimizes the repulsion between the electron pairs around the central atom, leading to stable molecular structures. Common examples of this geometry include methane (CHâ‚„), where the carbon atom is at the center, and hydrogen atoms occupy the corners of the tetrahedron.
